segfault on app creation #2330

Open kjmarshall opened 4 months ago

kjmarshall commented 4 months ago

Hi,

I'm not really sure what is going on, but I have a Cinder based application where I end up crashing. Strangely, I can control the crash by editing a fragment shader and changing how I mix colors with a texture. If I change from the operator* to glsl mix, the issue goes away. However I think the issue is deeper and possibly related to Cinder. The hardware on my computer is relatively new,

Here is the backtrace:

I can detect a GL_INVALID_ENUM very early in app creation -- i.e. when I call an override for AppLinux::AppBase::setup. This seems to imply the problem is with how the renderer is setup.

Is this a graphics driver issue?
