Mouse cursor size borrowed from desktop resolution, not game resolution

[CobraA1]

Describe the bug
Whenever I use my 4K TV with the desktop at a high resolution, the mouse cursor appears tiny in the game. This happens even when the game is set to a low resolution or high UI scaling.

Steps to reproduce
On Steam Deck: Connect to a 4K TV, go to display settings and set a 4K resolution. Then launch the game.

Adjusting launch resolution and in-game settings doesn't seem to make a difference, only setting the display settings in SteamOS itself.

Build version
0.86.2.3

Platform
SteamOS (on Steam Deck) is primary use case, although I was able to reproduce the issue on Windows.

Reproducibility
Easy to reproduce on the Steam Deck.

Logs/saves
Available if requested.

Desired behavior

• The mouse cursor should not be tiny at low resolutions; the size should be consistent with the scaling / resolution settings.
• Would like the mouse cursor size scale with the UI scaling - if I increase the UI scale at 4K resolution, the mouse cursor should scale as well.

The cursor in the game is rendered in hardware mode. This means its rendering is controlled by OS, not the game itself.

As a workaround, we can try to add an option to enable software rendering mode, but this mode has its downsides, like, it could move not as smoothly as hardware one due to inconsistent frame rates.

If you are using custom cursors, maybe you could have two or three sizes that the game selects depending on the circumstance (or on user preference, which might be easier to implement?).

Otherwise, I would like the option of a software cursor.

Having a tiny cursor makes it really easy to lose track of it. Almost unplayable on a game that largely depends on mouse / keyboard support.

It took some time, but finally the solution is here: we've added support for software cursor rendering in the recent
beta update. It respects the UI scale so this should definitely improve things for you.

You can toggle it in Settings -> General -> Use software cursor.
