In the 5.25 beta (5.24.90) under X11 I have square windows with no rounded corners. This is particularly obvious in GTK apps which have a large square outline. Context menus also have no rounded corners. This is fine under Wayland. It was also fine in 5.24.80 and on the git master.

I noticed that under System Settings->Display and Monitor->Compositor that "Compositing: Enable on startup" had become disabled. I re-enabled this and this problem has been fixed. Closing
