Hi there,

I have to set myself straigt indeed (axel):

The clipping info _does_ work in DirectConnected after all: I made a 
stupid beginners mistake :-/
Sorry about that.

The clipping info does NOT take the BMenuBar into account: I have to 
modify the clipping list to remove and/or modify clip_rects that are 
totally or partially in that range.
After doing that it's perfectly useable: no more drawing errors appear!

The second error in BGLView is that DirectConnect is called too late 
with the stop condition when the app is destructed. I need to check for 
existing clipping rects in the BView directly to prevent me from 
rendering _after_ BeOS updated the background. If view's clipping rects 
is zero I don't call the actual rendering code (testing that in 


OK, that's it: this is the final report on BGLView's direct mode...
