This occurs to every side that touches the boundary of plasmashell’s desktop:/ window. This means that every window which touches the boundary of the display, or a panel:

Importance

This is really problematic when attempting to acquire 16:9 screenshots.

It’s not the same issue exactly, but I wonder if this is somehow connected to the same underlying cause as 498597 – Using Active Window or Select Window mode, window top corners looks weird when using light variant of Breeze - something about borders not being captured or rendered exactly as they are on-screen?

I see the effect described in that bug report on your screenshots as well - although that report mentioned only Breeze Light, and yours seems to be happening on Breeze Dark?

@johnandmegh, actually, in this case, Spectacle is capturing exactly what’s rendered. When I tile a window to an edge, I see the window border wrap around the title bar, then stop at the window content, as depicted in the screenshots. I expect that this is a bug in the Breeze KWin SSDs. :frowning:

Thanks for linking that issue, though, because I’ve encountered that too, and that saves me reporting it myself. x

The cause is a Breeze window decoration default:

Strangely, like in t/44175, this solely renders the borders around the corners, now:

@UncleSpellbinder, you’ve no borders at all, however. That’s worse.

@rokejulianlockhart, Huh??

@UncleSpellbinder, kcmshell6 kcm_kwindecoration --highlight offers two options for window boundaries. To elaborate, whereas you refer to:

…I refer to:

Try disabling borders, but enabling outlines. I should have utilised more accurate terminology in the original post, in retrospect.

Well, I’m using Klassy theme.

@UncleSpellbinder, in which case, your situation is likely to be even less applicable, for Klassy doesn’t (yet?) render window decorations as Breeze does:

…and you’ve not configured it similarly, regardless.
