[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #1 from [email protected] --- I have the same issue, and I'm in a similar mixed refresh rate setup (180hz + 60hz) as @Dmytro above. But it gets even worse. In my case, I cannot even, for example, watch a video on Firefox on my secondary monitor without getting huge stutters on both monitors. Opening https://testufo.com/ on the secondary also has the same effect. It's so bad that even the mouse cursor stutters heavily on the primary when the video/testufo is playing. But curiously, if I move the mouse over to the secondary, everything becomes butter smooth. I have however noticed that after a reboot, I cannot replicate the issue. But after a suspend/sleep cycle, the issue is back. So I think this only happens after the system has been suspended at least once. Not sure if it's related or not, but in Plasma 6.8.0 instead of the stutter I got brief screen flashes on my secondary monitor. Those flashes are gone in 6.8.1, replaced by this new problem. Also, I see a lot of these messages being spammed in the logs: kernel: amdgpu 0000:03:00.0: [drm] *ERROR* Unsupported screen format RA24 little-endian (0x34324152) SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.8.1 KDE Frameworks Version: 6.31.0 Qt Version: 6.12.0 Kernel Version: 7.2.11-1-cachyos (64-bit) (also tested on vanilla Arch kernel) Graphics Platform: Wayland HARDWARE Processors: 24 × AMD Ryzen 9 9900X 12-Core Processor Memory: 32 GiB of RAM (30,9 GiB usable) Graphics Processor: AMD Radeon RX 9070 XT DP-1, primary: 2560X1440 @ 180Hz, scale 100%, VRR on, HDR off DP-2, secondary: 1920x1080 @ 60Hz, scale 100% -- You are receiving this mail because: You are watching all bug changes.
