I cannot reproduce the issue on my laptop with Ryzen 5 5600H. I suppose this is a graphics card driver issue. Not sure how to debug this, as we don't do low level stuff in Gala

This does not happen with regular Mutter 46 and GNOME

Here is the log file gala generated when I ran it headless from the TTY in wayland mode.

I started dragging a window at the 14:14 mark

Update - Gala takes up a considerably more CPU time while dragging windows around.

Update again: a few things to note

1. This seems to affect Libgranite apps as they also sometimes have visible frame drops
2. Using xdp-screencast makes Gala stutter

Ideas: maybe gperf could help?
