ABA's Brain Explorer and the OpenGL offset problem

[Bryan Bishop]

I've seen reports on appdb of SketchUp having the same problems. Have
these been resolved yet? I think this has been called the "OpenGL
offset problem".

B) The area between the window pane and the edge of the OpenGL window
never updates, collects copies of other windows, is butt-ugly.

5. Most secondary windows (Entity Info window stuck to left side of
virtual desktop)

If the OpenGL window offset problem could be solved this would be a
Gold app. As it is, a full-screen virtual desktop might give enough
workable space to allow the OpenGL window and plenty of tools open,
so I'm calling this useable with some tweaks and caveats.

What does not

1. OpenGL support appears to be broken; 3D window constantly appears
offset within main window with non-covered area not being updated.
Additionally, subsequent restarts show OpenGL window offset *further*
to top-left each time. Adjusting main window settings in registry was
ineffectual.

I've entered a test and will add some screen shots for this build,
but the main points are these:

2. The OpenGL window appears to be offset from the main window pane
position, but no amount of registry tweaking appears to resolve this
issue. Unless you resize the main window pain to just contain the
actual OpenGL window, you'll get a section of graphical "ghosts" or
copies on the bottom and left of the actual display, and your cursor
will also be offset.

Might be related to DRI in xorg.conf files?

This bug is maybe related with http://bugs.winehq.org/show_bug.cgi?id=13195 , which affects SolidWorks. http://appdb.winehq.org/objectManager.p ... n&iId=8983
It is a regression of the long-time known OpenGL child windows bug.

As far as i understand it, the issue is related to a bad management of multiples drawables or windows, especially with line redrawing in CAD applications.

I'm really surprised that no other 3D CAD apps are impacted. Maybe lack of testing ?
