Public bug reported: I have been experiencing screen flickering related to the compositor in KDE / Plasma on Ubuntu 19.10 on my Dell XPS 15 7590 laptop.
I found the same problem + a solution here: https://www.reddit.com/r/kde/comments/f7itw4/plasma_flickering_neonkubuntu/ It turns out that even though I do have Intel chip (IGP on Core i7-9775H) using the Intel driver i915, the package xserver-xorg-video- intel doesn't seem to be required and does cause screen flickering. Removing this package as suggested on reddit fixes the flickering issue for me and so far I didn't seen any negative side effects - all 3D rendering still works. Either xorg-video-intel package should be solved to not cause flickering (and have effects where it is not needed) or it shouldn't be installed by default. ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872192 Title: xserver-xorg-video-intel causes screen flickering in plasma on XPS 15 7590 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1872192/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
