A 1 pixel set of semi-random-looking trail is left when scrolling down (but not up).

Dave, is this a bug for you?

Comment 2

[David Hyatt]

No.  It's reported on the BeOS, so I'm giving it to duncan.

Comment 3

Afaik, the port has been updated to require BeOS 5.0.  At least, that's what I think all of the current developers are using.  I was unable to reproduce the bug in my latest cvs build.

This bug is back with a vengeance in Mozilla 0.9.7. I have found and corrected three off-by-one errors in the following files:/mozilla/gfx/src/beos/nsDrawingSurfaceBeOS.cpp/mozilla/gfx/src/beos/nsScreenBeOS.cpp/mozilla/gfx/src/beos/nsRegionBeOS.cppCurrently testing this fix. It is the cause of the missing line when scrolling, but also of the one pixel of garbage around all views, the missing bottom line of the URL history drop down menu, etc.

This patches the files mentioned above by Daniel.  Everything seems to be
working fine, now.
Can I get an r= on this?

Minor changes mentioned above

I see the problem now.	With the patch, the problem goes away but scrolling
seems to be a bit choppier (or maybe that's my imagination).   r=cls
