F3+S Confirm
F3+S Confirm adds a confirmation step before the F3+S debug hotkey dumps dynamic textures, so a stray keypress does not write files to disk.
What it does
Since 1.19.4, Mojang's F3+S hotkey dumps dynamic textures into the .minecraft/screenshots/debug folder, usually as dozens of images of a few megabytes each, which can take up considerable storage and cause lag while written. This mod adds a double-check to the hotkey so the dump only runs when the player confirms it. The mod runs on Fabric and Quilt for 1.19.4 – 1.21, and is client-side only, so servers need nothing. It is open source under the Apache License 2.0.
Key features
Hotkey confirmation
Pressing F3+S once no longer starts the texture dump; the player must confirm the action first.
Prevents accidental lag
Mistaken presses no longer write large batches of images, which avoids the lag spikes that accidental dumps can cause.
Confirm command
The f3sconfirm command lets a player choose to dump dynamic textures on purpose, or turn the hotkey off entirely.

How it compares
ChatLagRemover is also client-side only and open source under the MIT License, but it targets chat lag on 1.18 – 1.19.3 rather than debug hotkeys. Cmd Confirm is a Fabric-only, client-side mod for 1.21 – 1.21.4 that adds confirmation to commands under the CC0 1.0 Universal license.

What the author says
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…
