ELI5: Why is the mouse cursor slanted on a PC?
gpt
I believe it started that way due to a pixel resolution thing.  Having a clearly visible wedge with a precise point worked well, but when trying to design it in a vertical orientation, both lines looked wonky and blurred. Having the left side of the cursor go completely vertical to the screen made it possible to make a perfectly straight solid line, which gives the rest of the design more "structure".
