With "automatic" option it is easier to reproduce the issue but it also happens with "Always". https://imgur.com/VLtoTtL *** This bug has been marked as a duplicate of bug 479144 *** |
SUMMARY Launching a fullscreen application in wayland when adaptive sync is set to "Enabled" or "Automatic" causes the application to render new frames only when you press something on the keyboard or do something with the mouse. Basically it makes games unplayable. Running the game in gamescope or windowed mode with adaptive sync works fine. STEPS TO REPRODUCE 1. Set adaptive sync to "Enabled" or "Automatic" 2. Select any game that can be run in fullscreen OBSERVED RESULT Frames are being generated only when doing something with mouse and keyboard. EXPECTED RESULT Should generate frames the same way as when adaptive sync is disabled SOFTWARE/OS VERSIONS Operating System: Fedora Linux 39 KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 Kernel Version: 6.6.8-200.fc39.x86_64 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7735HS with Radeon Graphics Memory: 14.9 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: ASUSTeK COMPUTER INC.
