ROG Ally (Gnome): Some keys on touch keyboard are mapped wrong or behave wrongly

I use german as keyboard layout. I also have the same issue when i use the english layout (tried changing on keyboard and in gnome aswell): When i try to enter the @,€,²,³{,[,],},,~,µ or | sign the input behaves like i'm pressing arrow down. One would expect problem with the Umlaute, but no - they work just fine. Coincidence?: To type these signs on german layout you can use the "Alt Gr"-Key (which basically act as Ctrl + Alt). Also these are the only keys "Alt Gr"-key has mapping to at all (screenshot). But like i said the same signs on english layout don't work aswell. Also tryed to just use english an reboot. I had this problem since start. I think i have originally used the installer in german (41.20250216). Updated, changed the language - never worked in gnome. From within the gaming mode the touch keyboard just works as intended.
