Package: chromium Version: 46.0.2490.71-1 Severity: normal Dear Maintainer,
The Chromium GPU blacklist seems to be a bit overzealous and has too much faith in the software rendering code. I have been suffering from this bug for many months across multiple versions of Chromium, and the fix given in the same link works for me too: https://bbs.archlinux.org/viewtopic.php?id=181823 TL;DR: 1. Chromium Settings "Use hardware acceleration when available" Yes 2. echo 'CHROMIUM_FLAGS="$CHROMIUM_FLAGS --ignore-gpu-blacklist"' | sudo tee /etc/chromium.d/default-local "Severe artefacts" include my entire display being replaced, at continuous random intervals, with the previously active XScreenSaver even when chromium is not the active window or on the active workspace. Switching workspaces sometimes cancels the corruption, sometimes it doesn't, but after a few seconds it always comes back. It's not a very fun game to play whilst trying to work...
