this happens because the textures of the halves of the bed are non-adjacent in-atlas and the enchantment glint’s appearance depends on the location in-atlas that each texture it is applied to has. i believe this was implemented so that each item’s enchantment glint is unique but consistent.
hello, please find attached a video reproducing this in a singleplayer vanilla world, as well as the logs from the play session.
here is a video demonstrating the issue by going through a few dimensions. this is not the worst the issue can be, but still demonstrates very clearly huge spikes in frametime that were not present for me in previous versions.
here is my latest.log from the recorded session of gameplay
i have attempted changing some settings that may contribute to this, but anything i have tried has only made it worse, it seems my current configuration is the best this can get on this hardware. i used almost exactly these same settings in 1.21.9, .10, and .11, and this issue only started occurring once updating to 26.1.
i don’t understand how this could be working as intended. if flite is considered to be an optional dependency, then errors occurring if it is not present should be corrected, and if flite is considered to be a required dependency that should be reëvaluated as it is only necessary for a single function of the game, without which no other functionality is impacted.
can confirm in 1.21.5
can confirm in 1.21.2-pre1
can confirm in 1.21.2-pre1
can confirm for 1.21.2-pre1
can confirm in 1.21.2-pre1
i have attached a resource pack demonstrating the issue.
can confirm in 24w40a; this behavior is not present in 1.7.10
can confirm in 24w40a
can confirm in 1.21.1
this was unintentionally fixed in 24w36a
this does not entirely make resummoning the ender dragon impossible, but it does make it very difficult. here is a video demonstrating one way it can be done: https://youtu.be/bVBYrtisZAg
upon further investigation, changing the “chunk builder” setting from “threaded” to “semi-blocking” greatly decreased the lag spike
