Thanks !! I've reproduced ! Will fix it for next release

This still isn't fixed in 2116 for me, and I think I finally figured out EXACTLY what was going on. It only shows the context menu out of place when MM is maximized on the non-primary monitor in a multi-monitor setup. I have it set up so that the left of my two monitors (number 2 in Settings) is my primary, then maximize it on the right one (number 2 in Settings), and the context menu shows up at the left edge of the right monitor. If I switch my primary to my right one, so that #1 is primary (and restart, killing all processes), then it shows up just fine wherever MM is, no matter which monitor it's on.

This is such a fringe case, I hope you can find out what's going on on your end, but I won't gripe about it too much...

Edit: Nevermind about the monitor numbers, doesn't seem to make a difference to this bug. Just Maximized on the right screen when left is primary.

Thanks. Will be fixed in next build.

This was intermittent before the latest build, but now, it happens every time I try to right-click on a track in the now playing list:

As you can see, the context menu is opening up on the other side of the window. Only happens when maximized, though. Windowed works just fine:
