I've had some issues with areas of text/art failing to display and then somehow coming back later. Hard to describe :) But duhdraw works well enough, I suppose, even though I prefer the popup for picking colors and stuff in mystic.
I haven't used it a whole lot on the Linux side, and it sounds like there must be a place or two where it just needs to flush the buffer to the terminal. It should be a quick fix if I can see it happen.
In Windows the screen updates happen immediately and in Linux they are buffered, so sometimes I miss places where I need to push the screen update because I primarily develop in Windows.
If you have any way to reproduce an issue please let me know.
I'd like to make sure whats there is working well before I end up going back
to work more on block stuff and maybe some paging.
