Problems with round shapes on Mojave

[codeon-nat]

Hi

I tried out the example for "mac". I followed the instructions and it build without issues (once I used --recurse-submodules in my git clone statement).

But the output looks strange, and it seems that's whenever something is supposed to be round and filled:

I have a Mac mini (2018) with Intel UHD Graphics 630 1536 MB and macOS 10.14.6 (18G4032).

Try ensuring bit depth is 32 and stencil bits are 16 when setting pixel format descriptor. This fixed a similar problem running on windows 10.
