It happens for sure in the following applications (which I think rules out the application and toolkit, but not the compositor or Xorg):
* Firefox * Emacs * Electron apps (Keybase, Slack, Element) * Okular * OBS (maybe; this may be a different problem) * FreeCAD (maybe; FreeCAD has painting problems in general) * VMware (both the UI and the guest) Interestingly, I don't think I have seen any misbehavior in urxvt, which I use a lot. I am not using GNOME. My window manager is awesome and my compositor is compton. The mutter package is not installed on this machine. I will try to get more screen shots, although this is hard to capture because disturbing the window often causes a repaint. I have tried to capture video a few times, but as I am working with private information that does not belong to me on this machine I haven't yet captured an instance where there was nothing on my screen I am unable to share. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1893969 Title: Screen corruption and delayed update using onboard Intel video To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1893969/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
