SUMMARY Some applications in fullscreen flicker (white or black frame) when moving cursor between monitors or interacting with it. It does it with some games too (World Of Warcraft, Factorio). It doesn't happen when using other browsers (Brave or Falcon). It didn't happen when using 6.12 LTS. Journalctl doesn't show anything related while triggering this behaviour. STEPS TO REPRODUCE 1. Open Firefox in fullscreen (or a video) in multidisplay setup. 2. Move mouse between monitors. OBSERVED RESULT White or black frame is displayed, then draws properly SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.4.1 KDE Frameworks Version: 6.15.0 Qt Version: 6.9.1 Kernel Version: 6.15.4-arch2-1 (64-bit) Graphics Platform: Wayland Processors: 12 × 11th Gen Intel® Core™ i5-11400F @ 2.60GHz Memory: 32 GiB of RAM (31.2 GiB usable) Graphics Processor: AMD Radeon Graphics RX 9060 XT 16 GB Linux firmware: linux-firmware-amdgpu 20250627-1 Mesa: 25.1.4
Additional info I don't have adaptive sync active, primary monitor is UHD 60 hz, secondary is FullHD 75 hz. Also tried GNOME with same system and this doesn't happen there with same kernel.
Are you talking about the white flicker when rotating the camera in World of Warcraft (When your cursor hides)? Does this happen when you disable HDR and color profiles?
