What's the problem? Describe what went wrong.
When using gyro as a mouse on Steam Deck game mode, Mario Galaxy (or any Wii game) starts stuttering heavily after 30-40 minutes in the game. The stutter is worsened when moving the pointer. It seems to be related to having the mouse cursor set to pointer in Dolphin and then using the gyro as a mouse on the Steam Deck.

What steps will reproduce the problem?

Use the emudeck standard Dolphin settings.
Use gyro as a mouse in Steam gaming mode.

Is the issue present in the latest stable version?
Yes, the issue is present in the latest stable version.

If the issue isn't present in the latest stable version, which is the first broken version? (You can find the first broken version by bisecting. Windows users can use the tool https://forums.dolphin-emu.org/Thread-green-notice-development-thread-unofficial-dolphin-bisection-tool-for-finding-broken-builds and anyone who is building Dolphin on their own can use git bisect.)
