I've installed Texmaker 4.1 (using apt) on Ubuntu 14.04.1 LTS 64bits. Most of the time it works fine, but out of the blue it starts to show some strange behavior with accents marks, for example, I type "á ã à" and get "´a ~a `a" and other strange things.
Some people seem to have solved this problem simply by installing ibus-qt4, but I've already tried that and the problem persists, I tried a lot of font encoding options too.
Strangely enough, the problem goes away for ~30min if I close and reopen Texmaker, but that is very annoying... any ideas?
Thanks!
