It's a small annoyance, but I need to place my mouse cursor absolutely pixel perfect on the window borders to resize Opera windows (Opera 95.0.4635.37, GNOME, Fedora 37). I've heard that this could be because of Opera not using some sort of window shadow detection in GNOME?
Other apps function normally, the the mouse cursor turns into resize mode when 10-12 pixels from the border, esp coming in from the outside to the window.
