The mouse cursor is skipping when hovering over some applications. Every 4 to 5 frames the cursor doesn’t render. It’s as if the cursor is updating at a slightly lower rate than my refresh rate.
KDE desktop, KDE applications, and Steam are affected. Firefox, and games ran through proton, have normal mouse cursor behavior. Dragging windows has normal cursor behavior.
If I have a game running in windowed mode, and move the cursor off the game window and onto the desktop, the cursor moves normally. If I bring another app into focus, such as Dolphin, the cursor skips. If I move the cursor back over the game window, the cursor stops skipping.
If I do the same with Firefox and the desktop, there’s a second or two delay before the cursor starts skipping.
I tried using the kernels, linux-cachyos, and linux-cachyos-lts. Both have the same issue.
