[webkit-gtk] Minibrowser fails to start

[Peter Zhelezniakov]

Hi all,
I've built WebkitGtk on an Ubuntu 20.04 machine with Nvidia MX250, now the minibrowser fails to start. I have the latest Nvidia drivers installed and working AFAICT. Can it be the case that the flatpak environment conflicts with the 'real' libraries/drivers somehow? Is there something I can try to fix this?

Thanks! The error message is:
$ ./Tools/Scripts/run-minibrowser --gtk

(WebKitWebProcess:36): Gdk-WARNING **: 01:05:25.206: The program 'WebKitWebProcess' received an X Window System error.
This probably reflects a bug in the program.
The error was '167'.
(Details: serial 190 error_code 167 request_code 152 (unknown) minor_code 21)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
