Touchscreen on Steam Deck OLED is misbehaving in non-Steam games.

[Naxdy]

On my Steam Deck OLED I'm having an issue in non-steam games where the touchscreen is misbehaving in the following way: Whenever a touch is input, it registers that touch where the cursor was last let go, instead of the location I actually touched. Furthermore, the cursor has to be dragged before being let go, for the "location change" to be registered.

NOTE: The touchscreen is behaving normally in Gamescope and in the desktop environment (Plasma 6). Steam-native games have not yet been tested. Non-Steam games exhibit the erratic behavior described above.

Also, not sure if it makes a difference, but so far I've tested only Qt6 apps: Citra, qpwgraph, Dolphin Emulator

This problem was solved, at least for me, by adding gnome.caribou to environment.systemPackages

Perhaps this should be included by default?
