Lag spikes when accessing or closing inventory, chests, menus, chat, etc. (Wayland)

After I start Minecraft the menu gets laggy after a few clicks in the main menu. This continues throughout the game. Opening or closing player inventory, chests, menus, or chat, the game will lag for a bit over one second. Normally this is very smooth. Otherwise the performance is great. I attached a screenshot, where you can see the lag spikes in the extended F3 menu. (However, opening the F3 menu causes no lag spike.) I generated a new world and tested in different game modes, to make sure, that this is not a world bug.

I am happy to assist you reproducing this bug. If you need any logs or further debug information, please let me know.

Proposed workaround: Use Xorg instead of Wayland.
