Kwin Patched

Kwin With Triple Buffering Patch See on Gitlab

This COPR provides Kwin builds with the Triple Buffering Patch. This patch allows maintaining two frames in flight instead of just one, ensuring that your GPU is always active, reducing lag, and addressing slow animation problems.

According to the author, Xaver Hugl:

"When it takes more than one refresh cycle to render a frame, which isn't unheard of with weak integrated GPUs, KWin starts compositing immediately and we may or may not hit the vblank deadline. If it's missed, then the buffer takes a whole refresh cycle of the display to be used, which means the refresh rate drops to half of what it should be - resulting in a less smooth appearance and increased latency. With this MR, KWin schedules frames so that they can always hit the vblank deadline, and allows a maximum of two frames to be pending at the same time. This means that if the GPU can't keep up, latency will be increased just as much as is needed instead of almost one entire additional frame of latency and the halved refresh rate."

Note: This build is specifically for Fedora Rawhide and Future Fedora 40.
