Now I've tested kernel 6.8.12 with nokaslr

Stellaris is showing the input lag and the entire graphical user interface shows
the same input lag as long as stellaris is running.
Civilization 6 shows the same input lag as stellaris, probably even worse.
Magic the Gathering: Arena (with wine) works normally.
Valheim also works normally.
Crusader Kings 2 works normally
Rogue Heroes: Ruins of Tasos (a Zelda lookalike) works normally.
Baldur's Gate I & II and Icewind Dale work normally.

Also the input lag is only in the GUI, if I switch to a text console (ctrl + alt
+ Fn), input works normally even while the affected games are running.

Games aside everything else (e.g. compiling kernels) seems to work with nokaslr.
