Hello,
Localized the problem in the window creation/visual selection code.
(src/unix/video-drivers/glxtool.c/findVisualGlX)
A quick fix allows correct gldblbuffer switch function,
and ignores default/native visual id (since this isn't using double
buffering)
Somebody more familiar in this area to do a better fix?
With which radeon driver -/x window system/version is dri/hardware
accelerated opengl and multiple displays working?
Best regards,
Peter Trauner
