Known Issue - Vendor extensions drop down may not render well on some devices

[arunsivaramanneo]

This is a weird issue, If there are too many Vendors in the drop down the Drop down will not be displayed properly, there will be big blank space before the first vendor item, the Gtk ComboBox behaves oddly at different instance, sometimes it works just fine when user navigates to different Tabs and then comes back to OpenGL Tab, Sometime works fine when you click the ComboBox multiple times. The ComboBox seems to work good enough on Nvidia drivers, Mesa drivers are the one impacted most.

This seems to be a GTK issue, I have done some digging in google and looks like the GTK Team consider this as acceptable, even though lot of users reporting as a bug.Hope this will be fixed in GTK4.0 or i may need to move the ComboBox part to Qt. See https://bugzilla.gnome.org/show_bug.cgi?id=129463

This seems to be fixed with Gtk4 , needs Gnome version 43 and higher
