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

A user has reported in https://bugs.gnucash.org/show_bug.cgi?id=799816 that a
new Nvidia driver, NVIDIA UNIX x86_64 Kernel Module 580.178.04 of 7 July 2026,
crashes whenever they try to run a report. The old
WEBKIT_DISABLE_COMPOSITING_MODE=1 trick saves the day.
Since it’s a brand-new driver I think we’ll see more reports.
