Re: Creating many QGLWidgets causes GLXBadDrawable error in X Server
With the new 169.12 drivers under Linux (Fedora 8), I get a similar error message when trying to show a second (!) GL window. Only showing one works fine.
X Error: GLXBadDrawable 156
Extension: 143 (Uknown extension)
Minor opcode: 11 (Unknown request)
Resource id: 0x1800c87
This is with compiz running. If I disable compiz, I can show a second window. I don't have that many windows open though, so even if compiz manages them all as GL windows it should still be less than 20 (I think).
I will try reverting to 169.09 to see if that's any better, but I'm not expecting it to be.
