Yes, but WHY. It makes no sense that it works one way but not the other, melons and pumpkins are exactly the same >.>
No, it doesn't. My machine's max resolution is not 3360x2100, it's 2880x1800, so why on earth is the game playing at such a ridiculously high resolution? I don't even keep my scaling setting at that - it's meant to be scaled to look like 1680x1050. Attached is the Displays section of "About this Mac"
A: Just switched to the Vanilla launcher, same issue (no surprise) because it's an in-code issue.
B: If it changes the resolution to that high and Mojang is using it, they need to also utilize LWJGL's getPixelScaleFactor() instead of blatantly ignoring it - this is a new bug added since the LWJGL 3 update, and it needs to be addressed or else a large portion of the community playing on a Mac will have godawful performance.
No worries then. I'll have a Forge ASM fix for this when 1.13 comes out and Forge accompanies it. Leave it to the modding community to fix the game like usual ¯_(ツ)_/¯
Wouldn't be nearly as bad if it weren't for the AWFUL transition out of the game when alt-tabbing in Minecraft's fullscreen mode. The whole minimize thing is slow and distracting.
I'd like to leave this alone, but the bug is even worse.
I'm using my MacBook with a 4K monitor. It's SENSELESS for the game to try to play it at 2x resolution (7680 x 4320) and playing in full screen isn't a good option. Changing fullscreen resolution makes alt-tabbing take forever because it's changing the screen resolution back, and doing some minimize effect. Plus if in macOS's fullscreen and choosing Minecraft's fullscreen option, the game crashes.
Essentially, I question if the implementation of 1.13 on macOS was ever tested... I'd love to play it, but it's just unreasonably difficult to do so.
Update:++ Disabling biome blending solved this, and reducing it reduced the spike. I still don't understand why lighting has any effect on biome blending
