My guess is that the uniform bool lineSmooth is no longer true by default.
Maybe a solution is to remove this uniform and fix T81827: MacOS lines that should be thick are green instead in another way.

@Germano Cavalcante (mano-wii) yes the uniform default value is no longer. Just setting the uniform everytime should be enough to fix it. I don't think it is wise to search other workarounds at this time.

It seems I forgot to add the solution for 3.2 (or I didn't realize the problem is reproducible there too).
Working on it...
