You are thinking about https://bugs.kde.org/show_bug.cgi?id=433776, this was
shipped:
The spectacle part was in KDE Gear 21.04
https://invent.kde.org/graphics/spectacle/-/merge_requests/54
kwin part was in plasma 5.22
https://invent.kde.org/plasma/kwin/-/merge_requests/759
This issue is not the same.
Here it is about the drawing on screen of the selection area.
The rendering code in spectacle for this is suboptimal, so on a 2x 4k setup
this can show, especially on X11.
I am not sure this is a regression even, the rendering code was not really
changed with latest spectacle changes, but rather the first users with 2x4K
screens facing the shortcomings of the current implementation.
I don't have two 4k screens but I experience it somewhat with a 4k and a
2560x1440.
The solution for this bug is to rewrite the paintEvent of spectacle QuickEditor
https://invent.kde.org/graphics/spectacle/-/blob/master/src/QuickEditor/QuickEditor.cpp#L642
to be more efficient.
Around that subject we have also need to redo that painting to be per-screen,
to fix the mix dpr wayland case where the rendering gets blurry.
For those affected, Matt and Jason, do you experience the issue in a Wayland
session, or is it better or worse?
