Description slartibart70 2022-02-20 18:17:30 UTC 
Use chromium (x11-app) in wayland for this webpage.
Everytime the mousecursor hovers over some clickable links, the icon changes from pointer to hand.
But, this severly slows down the mouse movement.
Same happens, if you select text in a textfield with the mouse. This is all way slower than in X11

Anything we can do to have X11-similar performance other than waiting for chromium/wayland to appear?

Cursor updates have a much lower latency in Plasma 6, I think this is fixed
