What operating system are you running? Does this happen with any other textbox?

And does setting envvar OSU_SDL3=1 (Google if you don't know how) work? You can confirm that you set it right by pressing ctrl-f11 twice.

okay so i set it to sdl3

aand it fixes issue, im on Arch Linux, and without that flag (usual way) it does not appear in search text boxes but appears also in multiplayer chat text box
