As Axel increased BLooper's message queue to 200 today I was curious if that might not be what is the big problem behind our redrawing issue under Haiku. This because we may take a lot of time when dealing with messages which may allow it to fill up faster than we can manage. (Shame on us).
Luroh who had a freshly built version of Haiku tested and he said he didn't experience any redrawing issues. Update: Apparently it's still there.
After that we went for punch and pie. Not really, but this is my story. Anyway I suspect that this might be the case and I will probably run some tests. Feel free to come with ideas, fix the issue or just not read this post :)
