I remember these glitches being due to uninitialized variables.

Hello! Thank you for the heads-up about this glitching issue. If you don't mind, what system/GPU were the screenshots taken from? I can't reproduce on my Toshiba Windows laptop with Intel integrated graphics, or my Windows Surface Laptop with GeForce GPU , or my Samsung S9 smartphone.

In the meantime I'll take a look at my shader code for this demo and see if I forgot to initialize anything. Thanks again!

Ok thanks, unfortunately I don't have Apple devices like the MacBook that I can periodically test out my code on. At any rate, just now I went back and initialized some of the float variables in the CSG viewer fragment shader. Could you take another look and see if that helped at all? Thanks - sorry for testing by proxy! :)

Unfortunately, seems like the issue is still there...

Thanks - sorry for testing by proxy! :)

No worries!

Ok thanks for checking. I'll see if I can get access to an Apple device so I can debug more systematically. Thanks again for the heads-up.
