When placing an elevator i keep getting the "open GL error 1281" pop up in the chat, wich is quite annoying

.

I added this mod to an install of better minecraft [plus] 1.16.5 with OptiFine HD U G8 and the same problem occurs. It seems to cause a graphical bug that makes certain blocks invisible. It became too difficult to work around so I uninstalled ElevatorMod for now. It would be great to have a fix.

Same problem.
Causing by Optifine, can hide the msg by turning off 'Show GL Errors' at Options > Video Settings > Other.
However, the conflict still exist.

I think just by compiling with a newer version of forge fixed it, can anyone try this build to confirm?
