SUMMARY If I record my screen using gpu-screen-recorder with portal backend and play some games eventually cursor movement start to cause stuttering. Stuttering stops when I disable/stop GSR. Not any game is affected, I have this issue primarily in Arma 3. STEPS TO REPRODUCE 1. Start Arma 3 2. Start recording using gpu-screen-recorder 3. Play for a while 4. Start moving cursor. OBSERVED RESULT Cursor movement will cause heavy stutter. Interestingly, when "shake cursor" effect engages cursor movement doesn't cause stuttering anymore. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.21.0 Qt Version: 6.10.1 Kernel Version: 6.18.2-3-cachyos (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 9800X3D 8-Core Processor Memory: 64 ГиБ of RAM (62.4 ГиБ usable) Graphics Processor: AMD Radeon RX 6700 XT Manufacturer: ASUS ADDITIONAL INFORMATION I've got a feeling this issue somehow connected to VRAM saturation since Arma 3 is heavy on a VRAM, but in my video I didn't hit VRAM limit, and it still stutters. I can reliably reproduce this issue under heavy VRAM consumption scenarios. There's no such issue with drm backend of gpu-screen-recorder. I also using "RADV_PERFTEST=nogttspill" environment variable.

Created attachment 187948 [details] kscreen console log Just to clarify, I'm playing on 1440p 115% scaled HDR and VRR enabled monitor if that helps. Attached kscreen-console output.
Created attachment 188004 [details] Shake cursor stop stuttering Stuttering stops when Shake cursor effect engages. And when I move cursor to another while game window is active it's still stuttering.
