Big picture mode causing mouse cursor loss in some games.
E.g. Torchlight Infinite. I believe its caused by steamclient autohiding mouse cursor. Can we actually have an option to disable this behavior?

When running steam in normal mode, you can control mouse cursor anywhere with right stick, and cursor is visible.
When running steam on windows PC big picture mode (this also happens on steamdeck, as its running in big picture by default), mouse cursor no longer rendered, however right stick still controls it: you can see that elements are having on hover effects, just visually you cannot see where is the mouse cursor now. This game's controls horribly suck and relying on mouse cursor is really required.

Interesting thing is on SD running ProtonExperimental you can still control with screen touch, you will not see cursor though at all, only a second when you tap the screen. If you drag through the screen cursor also not rendered, however behavior differs on Proton9 (IIRC), and even mouse cursor is working fine there. Though game is rendered in invalid unoptimal resolution and I did not find the way to fix it.
