I just upgraded to the current upstream git (2011-05-12) and I don't see the problem either! > > *** Bug B > - Reported by dmg on May 7th > "This might or might not be related ... in some cases the > strokes are not displayed when created (but they are saved) > Only when the page is refreshed." > > I'll add to that: if I draw a continuous long line, the drawing > stops at some random point and from there on only small stripes or > blocks show the new lines.

I'm pretty sure this can't be an Xournal problem It's either an X server problem, or (more likely) a display driver problem. I'm going to follow this on Debian bugzilla for a bit and see what turns up. GI -- 100 THINGS I'D DO IF I EVER BECAME AN EVIL OVERLORD 40. I will be neither chivalrous nor sporting.
