Bug#1083019: gtk4 apps crash when using vulkan renderer with Nvidia hybrid graphics drivers

[John M.]

And just a little bit more information:

It seems the same issue was mentioned a week ago at this StackExchange
post: https://unix.stackexchange.com/questions/783899/debian-testing-gnome-47-nautilus-doesnt-start-anymore-why

And there's even a YouTube video that points to that same post for the
solution ---the solution being installing nautilus from stable.

One thing I noticed, is that some applications requiring a FileChooser
of some sort, cannot do so. I noticed it fist in the browser (Vivaldi),
but even when launching gnome-control-center from the terminal and
trying to select a file to change my user avatar, I get:

$ gnome-control-center 
13:21:17.6387 cc-system-panel[195017]: WARNING: Failed to pick avatar
image: Dismissed by user

That is, the FileChooser doesn't show up, but the control center
assumes the user pressed the Cancel button.
