I just upgraded (full reinstall inc. format) from 11.1 (32bit) to 11.3 (64bit).
Everything is working correctly except gmplayer (installed from packman).
If I play movies using gmplayer they do not play smoothly, but the strange thing is if I play the same file with mplayer from a terminal it does play smoothly.
If I play the file from a terminal with gmplayer no errors are reported...
Anyone here know what this might be?
