Timo: yes, sorry, I think I got a bit confused about packages due to lack of sleep. I've reported this against xserver-xorg-video-amdgpu for now although looking at the apt history it wasn't updated.
I'm not too familiar with the Xorg internals so any pointers on potential culprits would be welcome to narrow this down. We have 6 of these Lenovo E495 laptops all seeing the same issue. Originally I suspect the kernel since the first affected PC was on -25 whilst the 2nd was on -21 but booted with -21 and still affected. That was when we started looking at what packages had upgraded on the 1st PC and, later, when we realised 2nd PC was unaffected did a package upgrade on that (the 300+) and it was then affected. Must be something in one of those packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873895 Title: Regression: block staircase display with side-by-side monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libxcb/+bug/1873895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
