Description Guillaume Pothier 2008-08-11 00:04:58 UTC 
Version:            (using Devel)
Installed from:    Compiled sources

When (up)scaling is enabled and I do some scrolling or move windows around in the remote desktop, two kinds of artifacts appear:
1. Large vertical or horizontal one-pixel lines of garbage. This actually disturbs a lot.
2. Some areas are offset by one pixel. This is barely noticeable.

Attached is a patch for the first issue.

Fixes the one-pixel lines of garbage

This patch grows the update rectangle by one pixel in each direction to account
for rounding errors.
