I did an update this morning which installed the following:

Now google-chrome-stable Version 114.0.5735.106 (Official Build)
(64-bit) can lo longer display pages proplerly. It looks like chunks
of the application window are randomly scrambled or shown in the wrong
places. AFIACT, the pages are being parsed/process properly but the
actaul rendering of the X11 window is broken.

You can see examples here:

https://www.panix.com/~grante/chrome/bar.png

None of the other "big" X11 apps seem to be affected (firefox,
thunderbird, libre-office, etc. all work fine).

The console window where I launch chrome now spews almost continuous
errors like those show below. Has anybody else run into this? I'm
going to start backing out the updates above, but thought I'd check to
see if this was a known problem. I haven't found anything in buzilla
yet...
