Thunderbird 38.0.1 blurry fonts?

Question

Windows

Good afternoon everyone.
Today Thunderbird has been updated to 38.0.1 and everywhere the text has become blurry, if you select the text or move the cursor over it, then it becomes normal for two or three seconds, then blurs again. Video built-in hd4400, all drivers updated, Win7 x64.
Everything was fine before the update.
Tried disabling hardware acceleration, didn't help. On the screen is not very blurry yet, live stronger.
Tell me please, what could be the matter?

Answer 1

It helped to set layers.acceleration.disabled in the Settings Editor to true and restart thunderbird, in theory this is the same as the Use hardware acceleration option, but for some reason it was the switch in the Settings Editor that helped me

Answer 2

I read the question, updated to 38.0.1 - everything is fine with the fonts.
I will suggest reinstalling, since in your case you do not need to set up work with 100500 accounts.

Answer 3

Problem with scale, as an option try "Control"+"0"
