Your scene is very different from my bugs.

Don't know if really GL_EXT_packed_depth_stencil is really necessary here.

On my system looks like this:

https://ibb.co/T2ZWWZF

As seen, Manny as his shadow (the player) is rendered in front of wheels and stuff in the garage due to failure of depth testing. Same happen in other scenes.

The large stretch of the shadow is due to "no" stencil working.

Same here : https://ibb.co/HFPHY0J

At least some common ground between drivers. For glreadpixels failing with R300 maybe scummvm tinygl code can be used as an example for a workaround like converting the pixelformat to a working one before calling glreadpixel.

@BSzili
Can you check plz if you have the same problems on morphos build:
https://bugs.scummvm.org/ticket/13417

So we will know if it general big-endian issue, or platform specific

Thanks!

I continue to test, but ./ with MorphOS seem not a good idea.
