On CentOS 7 desktop, everything was working correctly with xorg-x11-drv-intel-2.21.15-13.el7.x86_64. Since I upgraded to xorg-x11-drv-intel-2.99.916-5.el7.x86_64, I get some random black texture appearing very quickly and spontaneously on the screen when an action is performed, eg. open Activities, print screen (with Prt Scrn button).
This is not 100% reproducible for some action but the Prt Scrn button action is, I would say, 90% reproducible. Sometimes, when opening the GNOME Terminal, the prompt is hidden, I guess due to a non refreshed texture or something like that.
