***


STEPS TO REPRODUCE
1. Enable the "Fall Apart" Desktop Effect in Plasma Settings
2. Launch spectacle (through application launcher or print screen shortcut)
3. Press Rectangular Region

OBSERVED RESULT
The window shattering animation completes before the region select shows
But the spectacle window shattered from the animation is still included in the region select
Proceeding to select a region with part of the spectacle window will capture the spectacle window

EXPECTED RESULT
Region select shows everything without the spectacle window in the way

Comment 1 Donald Davis 2023-08-20 16:54:28 UTC

To clarify, I meant I had originally found and reported the bug only testing Wayland. But now I have tested on X11 and have confirmed it occurs there too for me.

Comment 2 Nate Graham 2023-08-22 21:40:23 UTC

Fascinating; an issue with the timings of the animation, I guess.

Comment 3 Noah Davis 2023-08-22 21:57:37 UTC

As a quick solution, maybe we can blacklist Spectacle from the fall apart effect in KWin?
I think for a future proof solution, we're going to need some way for apps to request that they be excluded from compositor effects when doing certain things.

plugins/fallapart: Blacklist spectacle

Spectacle needs to be blacklisted in order to stay out of its own
screenshots.
