Nothing to add, really. Updated from b1 to b3 and boom. Windows are broken, but if dropped as items they are fine.

Ya, the new high-privacy windows ;-). Optifine installed? - because that's what I did not check.

Yep. Works fine without Optifine.

Ok, I'll have to have a serious word with my GIMP ;). Scheduled for the next beta.

Ok got it. Fix will be in v1.0.3-b4. And I have to remove the optifine flag, because I messed up the window rendering meself ;-). You just see it with optifine.

Thanks.

Ok, b4 is up. Could you also double check with your setup that the issue is solved?

Perfect, thanks for checking. I close this then.

Yep. Totally fixed.

Hi, the windows are now normal blocks and rendered with the (new) standard Mojang blaze3d. I currently do not see a handle where I could pull to fix it. Can you file this for optifine? (I think that's something to fix in the mod that messes with the graphics of others ;) )

Hello, with Minecraft v1.14.4, this bug is back. I have Optifine HD U F4 and Engineer's Decor v1.0.16-b5
