I have been looking at this, and I get the exact same problems, but only
with a couple applications.

I have recompiled and looked at the logs, but can't seem to fix this
issue.

I am still looking at it, and will do so again today.

I also noticed that somehow these programs seem to think the color is 8
bit.

Thanks,
