Custom cursors cropped and render at wrong size when monitor scale > 1

[MasonRemaley]

I'm writing a piece of software using SDL, though I've seen this problem in other software as well (e.g. Slay the Spire II has it.)

I'm not sure the correct terminology in Wayland, but if an app creates a custom cursor from an image it provides, and the monitor has a scale factor over 1, the following happens:

1. The cursor is rendered at larger than the expected size, resulting it in looking blurry
2. The cursor bounds are rendered at the correct size, resulting in it looking cropped

I wasn't able to capture a screenshot, because when I capture the screen with OBS the capture only replicates the first part of the problem. The same is true if I disable hardware cursors.

I initially filed this but with SDL, but after testing the same software in other window managers, I believe it's actually a bug in hyprland. Let me know if you think I'm mistaken, or if you need help reproducing the issue!
