Dear All,
I have an issue that was previously reported on you mailinglist here and not
answered:
http://sourceforge.net/mailarchive/message.php?msg_id=cbb4c0f20802191246o289
[email protected]
Specifically, I have a Qt application that uses 2D and 3D rendering in
viewports. Although fine as standalone, when used through VirtualGL, every
viewport (2D or 3D) is black. The only moment when I can see the proper
content is by creating a mouse event (movement, click and else), where it
flickers and for a second I can see the proper content before it becomes
black again.
I tried many combination of VirtualGL options but it seems not to do any
good.
The VirtualGL server is a SLED 11, although using few Suse OSS 11.2 repo,
64-bits and NVidia video card.
"from what have been said: It sounds like if the
OpenGL buffer is not flushed properly.
We are also aware of problems with some OpenGL drivers, beside the
ones from Nvidia, where setting the VTK rendering mode to "immediate"
may help."
But it didn't go any further in the thread.
Any help would be greatly appreciated.
Flo.
