Description Sergey Katunin 2026-02-10 11:35:17 UTC
SUMMARY

An example of such a case is when the rounding of the lower corners is enabled with no borders, and the window is magnetized to one edge of the monitor screen.

In this case, the rounding of the lower corner itself is turned off, but the rounding of the outline remains.

Overall, this is an minor problem, but still a visual flaw.

P.S I also wanted to suggest turning off the rounding of all four corners altogether (including disabling the rounding of the titlebar and of outline) - for such cases when the window is magnetized to one of the edges of the screen.

I've done this technically and can send a merge request, but I'm not sure if the developers will agree with this idea.

STEPS TO REPRODUCE
1. Enable Breeze window decoration
2. Enable rounding of the lower corners and 'no borders'
3. Magnetize the window to one of the edges of the monitor

OBSERVED RESULT

The outline is rounded, but one of the lower corners is not rounded.

EXPECTED RESULT

The outline of this corner should also not be rounded if the corner is not rounded.

Can confirm, since the tiling thing disables corner borders.
