Comment 8 for bug 1460027

So to summarize, you see the problem on your own build made with KiCad winbuilder and not on my MSYS2 builds?

Are you sure that you are running the correct executable while testing?

If not, please retest starting the exe from the file explorer directly. Otherwise, try to make a video of the issue, such that we can be sure that we don't see the same behavior.
