I'm running Thunderbird on a Debian/Buster system but my profile is
stored on a Debian/Stretch server. I've been doing it this way for years.
I last accessed my e-mail two days ago before upgrading both my server
and workstation's hardware (basically I got a new cpu/motherboard/memory
for my workstation and put the old cpu/motherboard/memory in the server,
replacing even older hardware). The video card is still the same. The
old workstation had an FX-6100 processor with 16G DDR3 while the new one
has a Ryzen 7 1700 with 16G DDR4. The server used to have a Phenom II
940 with 8G DDR2 but now has the FX-6100, etc..
The disk drives on both systems are the originals - they stayed with
their role.
When I brought my systems back up yesterday, everything seems OK (in
fact noticeably faster than before - including accessing files on my
network shares). However Thunderbird is almost unusable.
When I start Thunderbird, even in safe mode, it launches OK but the
panels don't draw themselves. I can sometimes get things to draw by
moving the mouse cursor over them. When I try to write or reply to an
e-mail, I have to frequently minimize it then expand it again to refresh
the panel so I can see what I've typed. Moving around in the various
accounts and folders in Thunderbird is also difficult. The screen
doesn't update when the elevator bars move or when I select a particular
message.
So far as I can see, Thunderbird is the only program behaving weirdly.
Everything else works great so far.
A person on a Mozilla support site suggested toggling hardware
acceleration but that didn't do anything no matter how many time I tried.
Any ideas?
