Update of the Mekanism issue I encountered:
The issue is repeatable with switching an end of a Mekanism mechanical pipe to "PULL". Fluid seems not to matter, just the pipes "PULL" texture. Testing in multiple single-player worlds as well.
Tried launching with different JREs:
- Oracle JDK 1.8.0_51 (bundled version) - No crash, but you can see that the texture is the problem. The mechanical pipe switches to the "PULL" texture, but there is that weird Texture Atlas effect overlayed on it. Had one that looked like an apple was stuck in the pipe!
- Oracle JDK 1.8.0_221 - Switch pipe to "PULL", instant crash
- Open JDK w/ OpenJ9 1.8.0_232 - Switch pipe to "PULL", instant crash
I removed Mekanism from the resource pack, but the problem still persisted. And if I load only Mekanism resources, there are no issues and everything works as it should.
I ran out of time to really dig into things, so I'm resorting to use the Thermal Dynamics pipe set for now. But I'd really like to figure out what is causing this, so if there are any suggestions please let me know.
