Public bug reported:
Hello, after upgrading firefox (and many other packages) on focal today,
I've got some video artifacts in firefox.
When typing in text boxes and text fields, the new character is drawn
very slowly, pixel-by-pixel, and isn't complete until the cursor has
moved on. When larger portions of the screen are updated, it looks a lot
like the entire window is being run through a video codec or you can see
parts of the video memory from other processes. (But it looks more
deliberate and predictable than either of these descriptions.)
So far Firefox is the only application I've found that is affected.
urxvt, libreoffice, xfontsel, glxgears all seem to work as expected.
I did get cairo package update today, but the changelog is just:
pango1.0 (1.44.7-1ubuntu2) focal; urgency=medium
* No-change rebuild with fixed binutils on arm64.
-- Matthias Klose <d...@ubuntu.com> Sat, 08 Feb 2020 11:15:23 +0000
And an xorg update:
xorg (1:7.7+19ubuntu14) focal; urgency=medium
* No-change rebuild with fixed binutils on arm64.
-- Matthias Klose <d...@ubuntu.com> Sat, 08 Feb 2020 11:21:28 +0000
So I don't believe these are involved.

Thanks
