Steps to reproduce:

(automatically) upgraded to 38.1.0
(1) moving up/down e-mail titles list in a folder
(2) double-click an e-mail title to open it

Actual results:

a bad gui behavior: text/graphic elemnts are not refreshed, black element/window contents.
(results of step 1) some e-mail titles dissapear (and then re-appear)
(results of step 2) specific e-mail window opens but not fresh: the window content is black. then, by slightly changing the window size i can see the e-mail text.

i have downgraded back to 31.8.0 in order to work normally.

Expected results:

normal gui behavior.

tsvikah, thanks for that info.

Do you still see a problem in version 45 with HWA enabled?

If you do still see problems, is it  better with (in this order)
1. current beta version from ?
2. latest NVIDIA driver  ?

I have enabled the HWA flag now (Thunderbird version 45.6.0 ; restarted, played a little), and everything seems OK.  
No problems found.
