I have a similar issue with Core i3-9100 desktop (Ubuntu 20.10 clean install) and a HP Probook 430 G6 (Core i5-82xx). Example: https://aws1.discourse-cdn.com/standard17/uploads/ubuntubudgie/original/2X/1/1f3f03e248964bc470caf7748cf7d8aa424474fc.jpeg
Might be the same as: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/1896627 because on the laptop, it mostly (but not only) happens when I use the touchpad or mouse and gets even worse when I scroll very slow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1896091 Title: [i915] Noise-like lines of graphics corruption when moving windows in Xorg sessions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1896091/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
