--- Comment #59 from Aaron Rainbolt <arraybo...@gmail.com> --- Writing this as a comment and not a bug report since there's still some more work to be done, but here's some extra info: While attempting to test the backports of this bug fix (https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/1178 and https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/2167), I used a special setup with a painfully slow emulated display in order to reproduce the bug and see if the fix worked. Initially, I was led to believe that the fix was failing in my testing, however on closer investigation, I believe there is a different though related bug that my setup is making show up. How to reproduce the setup: 1: Install GNOME Boxes. This virtualization software has been able to reliably reproduce the issue for me most of the time. VirtualBox has a significantly faster emulated display and may not work. 2: Install Kubuntu 22.04 into GNOME Boxes, providing 8 GB of RAM and 100 GB of disk space. (NOTE: KDE neon Developer Edition won't work - this bug only is appearing on Kubuntu for me, possibly due to the use of KDE Plasma 5.24 in Kubuntu, as opposed to a build from Master in Neon.) 3: When the installation is finished, do `sudo apt update && sudo apt -y full-upgrade` in a terminal, then reboot the VM. 4: Change the display resolution within the VM to the maximum possible resolution. 5: Place some widgets on the desktop. 6: Log out and log back in. The widgets will end up being shifted or scrambled around. 7: Download the KDE Plasma 5.24.6 tarballs and signature files from https://download.kde.org/stable/plasma/5.24.6/ and GPG verify them, then extract them. 8: Build and install all of KDE Plasma 5.24.6 once piece at a time, using `sudo make install` for installation. 9: Reboot the VM. 10: Place widgets on the screen where you want them (repositioning the existing ones if you so desire). 11: Reboot the VM again. The widgets will become scrambled/shifted again, as expected. 12: Apply the code changes in the two linked merge requests, then rebuild plasma-desktop and plasma-workspace. 13: Reposition your widgets, and reboot again. The widgets will become scrambled/shifted again, despite the applied bug fix. Note that, if you do this whole process on KDE neon Developer Edition, the widgets will never be shifted or scrambled around, *not even in step 11.* This indicates that this particular bug is outside of KDE Plasma, as two different distros running the exact same version of Plasma display different behavior. -- You are receiving this mail because: You are watching all bug changes.
