I see a similar problem, in addition to those described in #49. Glass panels in some colors do not connect. In the far building they are magenta color, and in...

When the world is loaded for the first time. And randomly when moving and loading new chunks

I also thought so, but after conducting tests, I made sure that this problem does not occur on the bundle vanila Minecraft + Optifine

strange, I have this bug occurs quite often. OK, maybe the problem is related to something else

Confirm. In my case deleting JourneyMap also solved the problem of drawing chunks

Managed to find a working test case https://github.com/sp614x/optifine/issues/5035
