Linus Lotz <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #26 from Linus Lotz <[email protected]> --- I also have this problem. I have a single 240 Hz monitor. It is less apparent when using a lower refresh rate (at 60 Hz I don't see the duplicate cursor but I see some flickering corruption around it, which is smaller than at higher refresh rates). I tried without success: - switching between "Prefer efficiency" and "Prefer color accuracy" - switching HDR on and off What also seems to fix it is to enable Adaptive sync, but that causes flicker on my monitor so I'd like to keep it off (maybe that improves with kwin changes for plasma 6.4).
