 **The issues below are relevant for ES-DE v1.0.0.**
 
-* On Linux, running games or emulators that switch the screen resolution may cause problems if ES-DE is run in Normal fullscreen mode, most likely due to driver bugs or possibly issues in SDL. Only a white screen will be shown when returning from the game and although the application is still running, attempting to navigate blindly will lead to a crash. Using the Borderless mode resolves the issue but removes the ability to switch windows using Alt-tab. Running ES-DE with the --window flag is another workaround, but that leaves the window border intact around the application window. Hopefully this issue will be worked around in ES-DE v1.1 as improving the fullscreen mode is planned for that release.

 * On Ubuntu 20.10, the included VLC version 3.0.11.1-2 is broken so ES-DE will crash when attempting to play videos. This can be fixed by manually replacing the file /lib/x86_64-linux-gnu/libvlccore.so.9.0.0 with the corresponding file from version 3.0.9.2-1 from Ubuntu 20.04. Make sure that the /lib/x86_64-linux-gnu/libvlccore.so.9 symlink points to this file as well. Hopefully this issue will soon be patched in libVLC so that this manual workaround will not be required.
 
 * On Linux, libVLC does not properly release memory when stopping the video player, leading to large memory usage for ES-DE. The memory utilization does not grow indefinitely though so it shouldn't make the system run out of memory and it shouldn't make ES-DE crash. As this issue is not present on BSD, macOS or Windows the assumption is that VLC is somewhat broken on Linux. The plan is to move from libVLC to FFmpeg for ES-DE v1.1 which will avoid this issue altogether.
 
 * The input configuration can be a bit glitchy on some devices, most notably the setup of trigger buttons for Xbox and PlayStation controllers. Once configured everything should work fine though. This configuration issue will hopefully be resolved in ES-DE v1.1 with the move to the SDL2 GameController API.
-* Some artifacts can be present with the gaussian blur shader, and screen tearing can be seen when using the slide transitions with certain graphics drivers and resolutions. Both of these issues mostly affect the upper part of the screen. The second issue is apparently more prevalent when running ES-DE at a lower resolution on 4K displays by using the --resolution command line option (which is only available on Unix). These problems will hopefully be resolved in ES-DE v1.2 when moving to the GLM library.

 * The launching of games can freeze ES-DE on some Windows installations. It probably only occurs on Windows 8.1 but that's not confirmed. The setting 'Run in background (while game is launched)' can be enabled to get around this problem, but this causes some other issues so it should only be used as a last resort. It's unclear if this problem can or will be resolved. If it's confirmed to only affect older Windows versions, then it's probably not worthwhile fixing it.
