The screen doesn't seems to refresh

[Mudito]

 When using the program in various situations sometimes the screen doesn't refresh, for example, you click on Reply and nothing seems to happen but actually, when you move the mouse over the screen, the place where the pointer is get refreshed with the new screen, if you minimize and maximize back again you find the screen refreshed as it should have from the beginning.

Found that in Firefox as well, but seems to happen more often in Thunderbird. I had problems with NVidia card, the update that came through the Update Manager didn't work so I had to download the full driver from NVIdia site and install it manually, don't know if that has anything to do with it.

Good luck!

Changing "layers.acceleration.draw-fps" to " true" helped but didn't solve it 100%.

Go Preferences> Advanced> General> Config Editor and then filter by "layers", change the value to "true"
