This has been fixed for a couple of releases now (since lunar I
believe), and if I recall correctly the issue was indeed the wpe backend
mentioned in comment 17. That would suggest this should be "invalid" for
gtk and yelp, and "fix released" for webkit2gtk.

Unfortunately I do not know the answer. It's been a while since I stopped
using ubuntu on raspberrypi and i went back to using the official system
for the device and since then I haven't changed system anymore. Also, for
other personal interests I haven't used raspberrypi so often lately.

Which package should be marked as Fix Released for 22.10?

Title:
Embedded browser display corruption under Wayland on Pi
One thing we changed in 22.10 is that we enabled the wpe backend, which
is the better maintained rendered and what upstream is testing. The non-
wpe codepath was even hitting errors on arm64 on recent versions as
described in https://bugs.webkit.org/show_bug.cgi?id=237636

I bare good news, On 22.10 current build for desktop, this issue no
longer is valid as it will be resolved! No more garbled mess. I have
been looking about but perhaps the fixes there can be applied to jammy.
Been testing 22.10 :D

I think this is to do with the hardware (probably 3D) acceleration under
OpenGL since the effect is reproducable by installing virt-manager,
setting the type to SPICE instead of VNC and then enabling OpenGL
hadware accelerated rendering (3d acceleration as it might be called.)
Thus, I believe
** Description changed:
- On the hirsute Pi desktop, under a wayland session with the "full" KMS
- overlay enabled, and "kms-modifiers" present in the

the recent update suggests the white rendering was indeed bug #1966418
which is resolved now

Title:
Embedded browser display
Another quick update: in recent days we've gone from "blank white space"
back to "incorrect stride corruption" in all documented cases (embedded
browsers, help windows, MiniBrowser, etc).
I note in the dpkg logs, libglx-mesa0 got updated a few days ago, but
unfortunately I'm unsure exactly when
@seb128 interesting, I've just tried this on a fully updated jammy image
on a Pi 400 and /usr/lib/aarch64-linux-gnu/webkit2gtk-4.0/MiniBrowser
starts quite happily; browser window opens and ... nothing but blank
white space within the body of the window. All the controls in the
toolbar are fine
@Dave, we believe that webkitgtk is broken on arm64 at the moment, at least the
surf autopkgtest are failing
https://autopkgtest.ubuntu.com/packages/s/surf/jammy/arm64
and the webkitgtk demo browser segfault when started on a canonistack
instance which I reported upstream as
Yes the yelp->gtk->opengl backend has probably changed over the past
year.

This still seems to be an issue on the current Ubuntu Pi Jammy images
although it presents in a different manner: instead of an incorrect-
stride corruption, the embedded browser (in the same places: help
windows, or the login entries for online accounts) simply appears blank
white.

Embedded browser display corruption under Wayland on Pi desktop
To manage
The same bug occurs in weston so that's some good news that it's not a
mutter bug.
The console output mentions GDK is unable to create a GL context and is
falling back to glReadPixels. And that's exactly what the corruption
looks like -- an incorrect stride or pixel format with glReadPixels.
That
The console output mentions WebKit and GL so it seems this is no normal
GTK app.
