Corruption regressed to the point that system would become unresponsive as the display flickered back and forth between an old and current state. If the system monitor app was running you could see the plots progress in an odd stop motion.
Tried a number of other distributions but kept getting corruption. Reverted the system back to Ubuntu 18.04, which was the last release that didn't have video corruption. Have been running 18.04 for a week with no evidence of display issues. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1886345 Title: [i915][snb] Icons and text corrupted and/or missing Status in gnome-shell package in Ubuntu: New Status in mutter package in Ubuntu: New Bug description: This is a fresh install of 2020.04. Issue is that the display routinely gets corrupted and flickers with blocks of previously open windows. If left without a restart, the system menu text will get replaced by odd characters and system dialog boxes will not display, buttons for the dialog boxes will briefly appear with no text when cursor is over them. Very occasionally, the system will stop responding to the mouse and keyboard after clicking an icon on the dash.
