This only happens when the secondary external display is operating at a different pixel width to the internal. In this case eDP is 1920x1080 whereas the external HDMI-A-0 is natively 1680x1050. It is caused by xfwm4's recent switch from using glx to xpresent for AMD GPUs. The underlying bug is in the AMD driver. I was able to reproduce on an external 1920x1200 display only when it was set to a non-native 1680x1050 resolution. --- Two identical Lenovo E495 laptops with 20.04 installed. The problem occurred initially on the laptop that is having package upgrades applied regularly. With dual monitors and the external monitor placed left or right the display has a blocked staircase effect shown in the attached photograph, and seems related to https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/-/issues/10 More detailed investigation suggests it only happens when the X coordinate of the two monitors is different. The symptom looks like an off-by-one error because it appears as if the display is divided into, say, 10 rows and 15 columns but the first row has 16 'columns' worth of blocks on it and so wraps to the beginning of the 2nd row, and so on. On the laptop without package upgrades being applied this didn't happen. So I upgraded it (314 packages) and restarted and it too sees the same problem. I suspected libxcomposite1 and downgraded it to 1:0.4.5-0ubuntu1 but that didn't solve it. I now suspect libxcb but so far haven't been able to prove it. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27 Architecture: amd64 BootLog: Error: [Errno 13] Permission denied: '/var/log/boot.log' CasperMD5CheckResult: skip CompositorRunning: None CurrentDesktop: XFCE DistUpgraded: Fresh install DistroCodename: focal DistroRelease: Ubuntu 20.04 DistroVariant: ubuntu GraphicsCard: Advanced Micro Devices, Inc.

The commands begin with a sleep of 7s, then switch to compiz (installed on my system), then sleep 7s and finally reboot.

[Bug 1873895] Re: Regression: block staircase display with side-by-side monitors of different pixel widths
Just tried upgrading my Xubuntu 19.10 desktop to 20.04 and I'm now getting the same staircase effect. Video card is an AMD Radeon RX 5700 XT which is connected with a DisplayPort -> DVI-D cable to an ancient LG W2252TQ monitor with a resolution of, yes, 1680x1050. It is the only monitor connected. Just thought I'd share. Rolling back to 19.10 now. I'll try again with the point release. -- 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 of different pixel widths To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1873895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've worked with upstream AMD and we've fixed the problem in in xf86 -video-amdgpu. As soon as that is available in the upstream repository I'll prepare a cherry-pick update to 20.04. I suspect we also need to consider an SRU patch to 18.04 ? -- 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 of different pixel widths To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1873895/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
