Major issue with Spray can

[u/Ok-Shop7510]

Basically, whenever I try using the spray can tool, it causes my cursor to become invisible, which applies to the rest of the brushes/tools afterward.

If I try to continue using the spray can, it results in MS Paint also painting in a different location and starts auto spraying even though I'm not holding down anymore, until I close MS Paint or click on something else.

Also, sometimes when I click the back button, there are some leftover pixels there that the back button forgets exist.

Does anyone know what is wrong and how I could fix this?
