Prerequisites

• [X] I performed a cursory search of the issue tracker to avoid opening a duplicate issue.

Checklist to make sure the issue is not on your end

• [X] The file ~/.config/gtk-3.0/gtk.css does not exist. (If it does, backup and remove it.)
• [X] I have logged out and in again.
• [X] Dark theme only. I have enabled adw-gtk3-dark in gnome-tweaks AND set the appearance to dark in gnome-control-center
• [ ] The flatpak theme is installed org.gtk.Gtk3theme.adw-gtk3 and org.gtk.Gtk3theme.adw-gtk3-dark
• [X] The app I'm having an issue with is an actual GTK3 app and is not coded using another toolkit like GTK2, GTK4, QT, etc.
• [ ] I have created a new user profile without any modifications except adw-gtk3.

Description

GTK3 software started looking like this about a week or so ago. The rounded corners are a GNOME extension. Disabling it doesn't change anything.

This might not be related to adw-gtk3 but I also started having issues with GTK3 software in general around the same time, where my mouse clicks aren't registered and I sometimes click through windows, focusing on what's behind it. Inkscape is barely usable.

I was able to fix the clicking through windows bug, which also fixed this bug. It seems to be related to Nvidia 550 drivers. Hopefully it doesn't come back. https://bbs.archlinux.org/viewtopic.php?pid=2151138
