Lasso tool 'retracing'

Hello everyone,

I had a question regarding the lasso tool. I have it set to polygonal lasso tool by default and use the alt-key to switch to the normal lasso tool whenever I want to. For a while now, when I use the lasso tool this way (holding alt) and make a selection, it retraces my steps when I let go without closing the loop. When I make big/complicated selection paths this can take up to a few seconds, which can be quite a nuisance. See GIF below for a visual:

I know it's a minor thing and I'm not even sure it's a bug, but if there's a way to get rid of it, I'd love to know!

Thank you all in advance 🙂
