Since 1.19.4, Mojang has introduced a hotkey F3+S to "dump dynamic textures".
Generally, dumped files are in the .minecraft/screenshots/debug/ folder, with mid-60s images sized around 1.6 MiB, and they will occupy more storage if you're modded.
Think if a player lags for mistakenly pressed this hotkey, no matter combating or crafting, the lagging will bring an awful experience.
In this mod, hotkey F3+S is disabled. And if you want to confirm dumping dynamic textures, type command /f3sconfirm.
