vgit-a9977

When using rounded corners via corner-radius = x, some apps show a weird border that is way off the edge of the app's window. It mostly happens on gtk apps and xfce4-panel plugins like power manager.

Steps of reproduction

1. set corner-radius to any value
2. restart picom

Expected behavior

No weird borders that extend way out of the app's window

Current Behavior

Weird border appears way out of the app's window

I think this is an interaction between rounded corners and gnome client side rendering. There is not much picom can do, but you can selectively disable rounded corners for gnome windows using rounded-corners-exclude

I've solved this problem due (refer to #572), it's just now that there are some weird things appearing on items on hover. Also happens on browsers

[KotonBads]

sorry I missed the wintype, shadows was enabled for tooltips

[peter-pedro]

I discovered it is due to frame background blur, therefore the following completely eliminates this issue in the most simple way: blur-background-frame = false;

how if i need include app for corner?
