Here you can see the digits

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:47.0) Gecko/20100101 Firefox/47.0
Build ID: 20160606113944

Steps to reproduce:

I updated Thunderbird from 1:38.8 to 1:45.2 using the Ubuntu repositories.


Actual results:

In all windows (including right click menu) there are shown three pairs of three-digit numbers. First and second change sometimes when moving the mouse, third is either 000 or 100


Expected results:

Nothing.

This looks similar to what I saw long ago when I had enabled a (graphics?) prefernce to display screen positions

It looks also like a graphic driver issue or what Wayne mentioned.

Daniel, please can you check if the HW acceleration is enabled (Options/Advanced/General/Use hardware acceleration when available? If yes, can you disable it, if not, enable it to check if something changes?

Yes, the acceleration is enabled. If I disable it, restart Thunderbird, the purple boxes are still there; so nothing has changed.

set layers.acceleration.draw-fps to false in about:config
(I guess you accidentally changed the default value)

Thank You! Thank You! Thank You! And no, I didn't touch the advanced config at all (I didn't even know Thunderbird has this feature until now)
