Hi All,
We have been having trouble running OpenGL Qt5 apps with VirtualGL including
2.4 beta1. One easily reproducible issue is the OpenGL examples supplied with
Qt5 don't resize with their windows when run with VirtualGL. This is seen with
both Qt 5.3 we built ourselves and the Qt 5.2 shipped with Ubuntu 14.04 in the
qtbase5-examples package.
On Ubuntu running the following command and resizing the window produces six
lines as per the trace below. Should we see a glXCreatePbuffer call if all is
working properly?
vglrun +tr /usr/lib/x86_64-linux-gnu/qt5/examples/opengl/cube/cube
[VGL] glXMakeCurrent (dpy=0x006c75a0(:1) drawable=0x01400006 ctx=0x0089fed0
