Anyone seeing this in current builds?

Yes, I'm seeing this on 0.9.9 and current builds (trunk) too. This off-by-one errors (horizontal lines missing) of fonts/images is reported on different bugs at bugzilla. (Mandrake 8.2 Linux)

Possible duplicate of bug 83289. That bug is almost fixed.

I get this in windows 2000 too (very often), with 0.9.9.

Moving to future since it unlikely to get serious attention for m1.0.

At least: this should be mentioned in m1.0 release notes with the hint that changing DPI settings can workaround it.
