[GNC] New Nvidia driver fail.

[Bruce Olson]

I have the same Nvidia driver, 580.178.04, causing GnuCash to crash when 
I try to run a report. WEBKIT_DISABLE_COMPOSITING_MODE=1 initially 
worked but stopped working today.

This is the Gdk-Message I get in the terminal when I try to run a report.
$ WEBKIT_DISABLE_COMPOSITING_MODE=1 flatpak run org.gnucash.GnuCash
Gdk-Message: 22:21:21.242: Error 71 (Protocol error) dispatching to 
Wayland display.

I used this search string "gnucash report crash error 71 wayland 
display" in DuckDuckGo and found this.
https://docs.defguard.net/support-1/troubleshooting-guides/desktop-client/client-crashes-immediately-on-launch-with-error-71-protocol-error-dispatching-to-wayland-display

I tested their workaround:
WEBKIT_DISABLE_DMABUF_RENDERER=1

I launched GnuCash in the terminal with this:
WEBKIT_DISABLE_DMABUF_RENDERER=1 flatpak run org.gnucash.GnuCash

Now I'm able to run reports again.

I can add a comment to Bug 799816 if this would be helpful.

Regards,
Bruce
