Hi, I just updated to Tumbleweed 20170529 from whatever the current-minus-1
release was, and Thunderbird is now unusable. It has major graphical glitches
that obscure most of the interface. The UI elements sort of flash and
appear/disappear as I move the mouse over them. This is an example of what I'm
seeing:

(The only think I modified on these screenshots was blurring my personal
information. The large grey rectangles and abnormal white patches are from this
bug.)

I tried disabling all extensions (I only use one), and I confirmed that I'm not
using any custom Thunderbird skins. Also I tried reverting to Adwaita. I also
tried switching from the modesetting Xorg driver the Intel driver, and I tried
both Intel SNA and Intel UXA acceleration. None of these changes made any
difference.

I was able to work around the issue by reverting to this old version I found
here:
