i don't know if this belongs to the same bug, i rather ask before opening a new one.
if i'm playing vdrift in fullscreen or window mode (doesnt matter), and have music running, or especially when a libnotify-popup comes up (from IM), there is a huge annoying jitter, which then exists, as long as vdrift is running. only restarting fixes this. i fiddled a bit with the settings. the music volume was at 0.40 and the sound at 0.9. i turned the music volume to 0, which made this aknowledgably better, but didnt totally fix it. when the libnotify popup came up, jitter then started again as bad as it's been before config tweaking.
The Jitter sounds a bit as the issue described in this bug, like when the other cars already are a bit at distance.
hints?
