If the issue is more prominent when the cursor is showing, it could be the hardware cursor (default on KDE) causing the issue. When you use hardware cursors, the cursor is rendered on a different ‘plane’ on top of the rest, possibly causing desync. You could try disabling it with a environment variable (I think it was KWIN_FORCE_SW_CURSOR=1), forcing to software render the cursor.
