SUMMARY

This is essentially the same bug as  https://bugs.kde.org/show_bug.cgi?id=456280, which somehow got fixed at least for one person in Plasma 6.0.4 Wayland.

For me windows are still not redrawn within the WindowHeap effect on two fully independent systems and installations,
when they reside on a virtual desktop, which is not the currently active one.

I've tested it with various applications such as Konsole (with htop), Firefox, Chromium and OBS Studio on Wayland only.

Comment 1 Zamundaaa 2024-05-28 18:18:26 UTC 
Can confirm with Qt apps, but not with glxgears. I think it's because the window isn't considered exposed, so the apps don't render

Still works with VLC
