I see this in firefox (123) menus when moving the mouse through the menus: the highlighting of the entries doesn't get painted right away. It kind of looks like some cached written data doesn't get pushed out to the final destination right away. The same could explain the mouse cursor. nia@ suggested to run xcompmgr. It fixes the Firefox menus for me, but not the mouse cursor. Also it breaks my use of xv (graphics/xv) to set my desktop background (and change it every 5 minutes). I'm trying to use feh for that now. With this config (kernel 10 + intel hw + modesetting driver) the x11/redshift program doesn't work any more (it works on my Thinkpad T470s with kernel 10 + intel hw + intel driver). -Olaf. -- ___ Olaf 'Rhialto' Seibert <rhialto/at/falu.nl> \X/ There is no AI.
