Hello there,
while testing my "Optimus" Notebook i saw a stack trace in my logs,
maybe someone is interested!
I can easily reproduce this any time. It happens when offloading a GL
app, here Unigine Heaven 3.0 to the nvidia card. To be more exactly:
When starting Unigine the window stays black. To get something useful i
have to minimize and maximize the window. Exactly when maximizing the
window the trace happens.
Hope this helps anyway!
