I forgot to mention it also happens when starting programs. > - Try X11 (this actually helps, but I wish to use Wayland)
Input latency issue maybe.
Doesn't seem like latency problem. It's Logitech MX Master 3S and in other situations works perfectly. Seems to me like something is halting UI process. I am also seeing this issue I've found that I can eliminate the cursor lag by either changing the KDE compositor mode to "balance of smoothness and latency", or by switching my laptop's graphics mode from hybrid to dGPU. James thanks for the tip. Setting "balance of latency and smoothness" seems to help. I upgraded to the 6.5.2 kernel a few hours ago and this problem (so far at least) seems to have disappeared. Great! FWIW it should also be much improved in general in Plasma 6, which includes a variety of cursor smoothness fixes. So far looks good also for me when I upgraded to kernel 6.5.2. This seems to be a great kernel, because it works much better with my Zen3 processor. Maybe this issue was visible only on Zen processors. It was happening to me on an intel based laptop so I don't think it's related to the zen changes. Not really sure what exactly fixed it but happy to live in ignorance so long as it keeps working! |
