Bug Description

This line:

loadPrcFileData('', 'window-type offscreen')

as well as the following:

base.win.makeTextureBuffer("buffer", 256, 256)

makes the Python interpreter crash.

With "gl-debug true" and "notify-level-glgsg debug" in Config.prc, the output is as follows:

:display:gsg:glgsg(debug): Creating depth stencil renderbuffer.

A workaround (at least for the base.win.makeTextureBuffer problem) is to do the buffer set-up differently, and either create a depth texture to attach to the depth slot, or request a 32-bit depth buffer, to prevent it from creating a depth-stencil renderbuffer. This seems to suggest a crash in the code that sets up a depth-stencil renderbuffer.

This bug affects me too. I found it while tried to setup tobspr pipeline:

https://github.com/tobspr/RenderPipeline/blob/master/data/default_cubemap/filter.py

Looks like it intel HD built-in graphics card specific. My is Intel HD 4600.
