Pressing shift permanently enables precision mode

[Aroweeri]

fSpy versions: 1.0.3, 1.1.0-beta.3
OS: Manjaro Linux (updated 2024-04-10)
Using the AppImage release downloaded from Github

I'm brand new to fSpy, just following the tutorial. When I try to move the vanishing point handles, I can move them fine. When I hold shift to position them with precision/magnifier tool, fSpy get's stuck in precision mode.

Releasing the mouse will hide the magnifier and release the vanishing point handle, but trying to grab it again will always enable precision/magnifier mode, whether or not shift is held down. This makes it very hard to use the tool.

I can get the behavior to change by clicking File->New and loading the example project. In the new project, clicking and dragging becomes fast again as if shift wasn't held down, but the magnifier still shows up every time I click and drag a handle. Pressing shift will permanently enable precision mouse control like before. No amount of button-mashing will make fSpy stop using precision mode.

Currently trying to compile the source to test that as well.
