SUMMARY After installing the current Plasma Beta on Tumbleweed, it appears as if the screen rotation bug on Wayland has either regressed or was never really fixed entirely: https://bugs.kde.org/show_bug.cgi?id=425796. See the linked report for a more detailed description.
Please do one of the following: - If the issue described in Bug 425796 is exactly the same, re-open it with a comment - Otherwise, fully describe the issue fully here
I will reopen and mark this a duplicate then. I wasn't sure whether reopening was the correct thing to do here, as the issue appeared to have been fixed in the past when I tested. But the symptoms are the same. The only difference is that I experience this on openSUSE Tumbleweed (in contrast to Manjaro or a compiled from master session there where it was no longer occurring). *** This bug has been marked as a duplicate of bug 425796 ***
