Hi, the default hardware acceleration policy changed from
WEBKIT_HARDWARE_ACCELERATION_POLICY_ON_DEMAND to
WEBKIT_HARDWARE_ACCELERATION_POLICY_ALWAYS. I think you need to add
"--device=dri" to the finish-args in your flatpak-builder manifest:
https://github.com/flathub/org.gnucash.GnuCash/blob/master/org.gnucash.GnuCash.json
so try that. If that fixes it, let us know and I'll post an
announcement to remind other maintainers.
Alternatively, you could use
webkit_settings_set_hardware_acceleration_policy() to select
WEBKIT_HARDWARE_ACCELERATION_POLICY_NEVER to disable GPU usage. This
option will go away with GTK 4 though -- WebKitGTK will always require
GPU -- so probably better to leave it enabled and shake out any
problems now.
Hope that helps,
Michael
