Does this happen with any other applications after waking from sleep? I think that it must be a Wayland bug - there is no way that KAlarm itself could request its window to appear like you report. KWayland is a specific library that is (in general) is not the cause of wayland problems. Please do not put general wayland bug reports there Recategorizing as KAlarm. Robert, are any other applications displaying with the same kind of window corruption? @TraceyC: Could you please explain how you think an application could produce window corruption like this? I wouldn't have thought that it was possible, and that it must be the compositor or window manager or some such thing. That's why I reassigned it to Wayland.

I'm not one of the maintainers of Wayland or KWin (which does window compositing0, nor am I an application developer, so I can't tell you how an application can cause window corruption. In the HTML / CSS world I've seen that when libraries change, positioning can be thrown off and the code has to be updated to adapt. I don't know if that's the case here. Tobias already confirmed this is not caused by KWayland, the library, so putting this back in that category isn't going to move this bug forward or get it in front of people who might be able to help. I'll move this to kwin, they can confirm whether this is a compositor bug or not. Robert, please let us know if this happens with any other applications. Thanks. |
