The game lags when navigating through inventories and menus while playing in windowed mode. This issue has been occurring on my device since version 1.21.6 (without mods).
After disabling the Menu Background Blur option, the problem stopped for a few minutes but then returned, so it doesn’t seem to be related to that setting. This bug does not occur while playing in full-screen mode.
Steps to reproduce:
Set the Menu Background Blur to its default value.
Join a world, open any inventory or menu, and check if lag occurs when opening sub-menus or other inventories.
If lag is present, switch to full-screen mode and verify if it stops.
Additional info:
Although I listed those steps, the issue doesn’t seem to occur on every device. My PC drivers are up to date. For reference, my system specs are: AMD Ryzen 5 5600X 6-Core Processor, NVIDIA GeForce RTX 3050, running Windows 11 in the stable release.

We do not have enough information to find the cause of this issue.
While the lag occurs, please press F3 + L once, then wait a short moment until profiling has finished.
Afterwards, please attach the generated .zip file containing the profiling results here. The file path is shown in chat; the file can be found in minecraft/debug/profiling/<DATE>.zip.
If you are playing on a server please additionally run the command /perf start to create a profiling report for the server. In case you do not have the permission to run this command, make sure that you're a server operator.
Once profiling has finished, please attach the generated .zip file from debug/profiling/<DATE>.zip of the server folder.
This issue is being temporarily resolved as Awaiting Response. Once the requested information has been delivered, the report will be reopened automatically.
