Description Colin J Thomson 2025-07-20 18:36:10 UTC
Running git master. 
Not sure if I have chosen the right component.

I have noticed with bottom rounded corners enabled, I cannot grab the bottom, left or right edges to resize the window. The top corners and top edge work fine. 
Tested with Dolphin, Falkon, system Settings etc.

If I disable bottom rounded corners all works as it should and I can grab any edge/corner to resize a window.

Works for me. Are you using any custom window decorations or non-default window decoration settings? What scale factor are you using? Does the issue reproduce in a new clean user account?

No, I always test with default settings/decorations etc and a new user account when submitting bug reports.
However this seems to be fixed now, but I cannot find the setting I used before to turn it on/off. All I can find is an option in Breeze decorations options.
I guess this can be closed now?

The setting is in System Settings > Colors & Themes > Window Decorations > Pencil icon for Breeze theme > "Round bottom corners of windows with no borders"
