--- Comment #9 from Giorgio Loi gioloi72@gmail.com 2008-04-06 05:13:34 --- I repeated the regression test to investigate about the OpenGL offset issue, and this is what I got (details in attachment):
winex11: Update the win data rectangles before doing anything else in SetWindowPos.
Tell me if I should open another bug thread for this..
Solving both the issues ChosePixelFormat and the OpenGL offset, permits to Sketchup to work fine.
This is a brief description of the openGL issue: in the drawing window anything is drawn with an offset to the mouse position, so it's impossible to work because to draw a line in a position you should position the mouse staggered respect to the point where you want to draw.
Excuse my english
