Tema dinámico FAQ

Windows does not allow all applications to run in the background automatically - or you may not have granted this permission in the past. The application needs to be able to run in the background to perform updates automatically according to the settings you have chosen. Follow the directions available in Automatic Troubleshooting Utility available from the application's Information menu.

With Windows 11, Microsoft removed the global menu and hide the background task permission setting for applications. You need to go to the advanced options of the Dynamic Theme app (Windows Settings > Apps) to change this system setting.

If you had globally disabled background tasks with Windows 10 and then migrated to Windows 11, the permission will be missing from the advanced options. Manual removal of the GlobalUserDisabled key in the HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\BackgroundAccessApplications branch of the Windows registry is required as there is no longer a graphical interface to do this (reboot required afterwards). A tutorial is available here if you need.

Background tasks are constrained by Microsoft to run quickly (less than 25 seconds). To update your background/lock screen, the slideshow option must enumerate your files, and this process can take more than 25 seconds in certain circumstances.

To ensure fast file enumeration, you need to make sure that in Windows Settings you have enabled enhanced indexing (or make sure that your directories are not in the exclude list). See this tutotial here. The applications automatically take advantage of indexing and enumerations will run faster in this case.

Also, make sure that the number of pictures is not enormous - if it is, it's best to spread the images over several directories.

To validate the option's performance, you can manually click on the update button inside the application to see whether or not execution is fast.

This behavior is not necessarily active by default, however, an option in Windows allows you to enable it. Go to the system application 'Settings' > 'Personalization' > 'Lock Screen' then make sure the option 'Show lock screen background picture on sign-in screen' is enabled.

This version of Windows 10 has a issue with background tasks that manipulate visual (like pictures) objects. Please, install the last updates available for this version of Windows to get functional background tasks for automatic pictures changes. Windows Insiders builds also have this issue (17692.0 - 17763.6xx).

The synchronization option in application only allows you to synchronize your settings and not the pictures you're using. Following the received requests, an improvement of this feature is under consideration.

Applies to Windows 10 only - Windows 11 no longer offers this option.

Microsoft has implemented an option to synchronize your theme between devices of the same family. If this edge effect does not match what you want, this option can be disabled manually from the system application 'Settings' > 'Accounts' > 'Synchronize your settings' then uncheck the option 'Theme'.

Windows 10/11 has an option called 'Battery Saver' which extends your battery life by limiting certain system services and limiting the capability of applications to run in the background without it being able to oppose to it. The application needs to run in the background to retrieve new pictures and update your settings according to your preferences. If the 'Battery Saver' option of Windows 10/11 is enabled, the proper run of the application is no longer be guaranteed.

Most of the VPN solutions do some level of DNS filtering to optimize their traffic. The Windows Spotlight Microsoft feed is often categorized as advertising by the VPN solutions and blocked.

Check your VPN settings and ensure no filtering is enabled. Some solutions hide the filtering behind a threat protection.

All the required endpoints are indicated in the next FAQ item.

Theses URLs need to be whitelisted:

• https://apps.pinnula.ca/* (for links, changelogs, updates management, FAQ and contact form)
• https://www.bing.com/* (for Bing pictures)
• https://cn.bing.com/* (for Bing pictures, specific to China)
• https://arc.msn.com/v3/Delivery/* (for Windows Spotlight pictures)
• https://fd.api.iris.microsoft.com/v4/api/* (for Windows Spotlight pictures)
• https://arc.msn.com.nsatc.net/* (for Windows Spotlight pictures)
• https://*.akamaized.net/* (for Windows Spotlight pictures)
• https://res.public.onecdn.static.microsoft/* (for Windows Spotlight pictures)

The application will work correctly most of the time, but it is not possible to ensure that will be the case all the time because Microsoft can change the URL of one or all the pictures dynamically anytime.

The pictures used by the Edge browser's home page are taken from the 'Windows Spotlight' feed that the application already supports.

Contrary to the Bing pictures, the Windows Spotlight pictures are completely random and not associated to you or your device. This explain why a different picture can be used on the same computer with two user accounts or on your other devices. Also, the history is not ordered in the Microsoft feed. We are investigating how we can improve this area in a future version of the application.

This is a new feature of Windows itself introduced by Microsoft with the April/May 2024 updates. You can read this Microsoft page to discover the new feature.

To disable these new cards, open the Windows Settings then go to Personalization > Lock screen > Lock screen status and select None.

Microsoft does not publish all the pictures in all resolutions: the Bing pictures are available in HD, Full HD and Ultra HD (4K) but not always. The Windows Spotlight pictures are available in Full HD and Ultra HD (4K) since the update 1.7.99 of Dynamic Theme application.

The application uses the best resolution according to your display.

It's unfortunately impossible to implement this support because Microsoft doesn't expose APIs to developers to access and modify the settings of each screen separately. A single API simply tells the system to use an image as a background and/or lock screen.

If an API is added in the future, this support will be implemented.

Unfortunately, this is the behavior of the official Windows API that can be used by third-party applications when they are launched. When the automatic update is performed in the background (application not launched), the change is applied by Windows to all virtual desktops.

Unfortunately, it's impossible to implement any update of your accent color according to your current picture because Microsoft doesn't expose APIs to developers to access and modify this setting.

On PC, you can bypass this by manually activate from the system application 'Settings' > 'Personalization' > 'Colors' then by checking the option 'Automatically choose an accent color from my background.

On Phone, there is unfortunately no manual option to activate to get around it.

If an API is added in the future, this function will be implemented.

This is now resolved/supported with the version 1.5 and beyond 🎉

Microsoft does not embed any watermarks in Bing pictures except for the 1920x1200 format when the it is available (not systematic). The application using the most appropriate picture depending of the resolution of your screen, it is possible that this format is used hence the appearance of the watermark.

With version 1.5 and above, an option allows you to use the best picture quality available without watermarks.

Only markets that have a specific picture every day are listed, use the 'current culture' option to use your culture and see the specific pictures that are sometimes available on certain occasions.

Unfortunately it's impossible to translate the application in all languages because it's distributed free of charge and we aren't speaking all the languages. However, if you want to contribute to translate the application in your language or fix an existing translation, don't hesitate to use the contact form available at this address. We will happy to integrate your contribution, thank you!

When you use a RDP connection, the display resolution know by Windows is the native resolution of the real device (builtin display for a laptop, default value for a computer/server). The RDP connection handle the resolution on their own. Related to that, Microsoft hide the display information in the native Windows Settings when a RDP connection is used for example.

The dynamic display management feature of the application can't detected correctly your current display resolution in this context. To prevent bad picture quality, you need to disabled the option in the menu About > Extend Display settings group > Disable the option.
