This doesn’t appear resolved. In fact your “test” comment in which you claim to have failed to reproduce this, does actually reproduce the issue on my end
[media]@GoldenHelmet no that should be reported separately
Video of new reproduction steps now that the related issue is fixed:
[media]Insight from RaphiMC:
”The buffer upload regression in 1.21.5 does not affect all systems. It mostly affects Apple GPUs. Avoiding glBufferSubData on all systems causes a performance decrease on most GPU drivers. ImmediatelyFast <=1.21.4 in fact even has an optimization which replaces glBufferData with glBufferSubData because its measureably faster on most systems.
It should be noted that 1.21.5 has multiple other performance regressions, even ones which affect all GPU vendors, so direct comparisons between 1.21.4 and 1.21.5 even with the buffer upload fix are not possible.”
Dear Macka. I implore you to be more thorough with your role on the bug tracker. The “suggested fixes” you speak of were posted by an AI bot and were clearly nonsensical and irrelevant. The comment is now deleted, presumably by another moderator.
To futher clarify, the comment mentioned OptiFine which is a Java Edition 3rd party mod and not applicable to Bedrock Edition. Lowering render distance or mipmapping should have no effect on stars and Vibrant Visuals does not have motion blur
Lastly yes, this is still an issue in the latest version
Can confirm. Also this isn’t exclusive to the lava cauldron. the water cauldron is also affected, you can use it to extinguish yourself via the same manner,
Actually can reproduce.
This issue appears to be VERY closely related to MC-279284
I couldn’t reproduce it before because I was throwing the bottles against a flat wall. But it does still happen when throwing the bottles against a corner (because they still get stuck inside blocks in that case)
Cannot reproduce in 25w18a
Can confirm in 1.21.5 and 25w17a
I am not using any add-ons or resource packs
video settings
This is fixed in the latest preview
and I am not using any add-ons or resource packs
Much easier to see that the issue was fixed in a tall world
[media]Yes but only if Volumetric Fog is turned on
And it’s much less severe
Based on this I have a theory these links do work for people with special permissions (Mods, MCQA & Mojang) so I would implore to attempt reproduction on a regular user account without any privelages.
