A video showing the icons flickering. Watch Signal Desktop Beta in the first half of the video.

SUMMARY
When moving the mouse from one folder-menu item to another, some icons of the first submenu are shortly visible in the second submenu. It seems to happen at the location of a separator in the second submenu. 

It is somewhat hard to explain, but a video is attached. At first, keep your eyes on the icon for Signal Desktop Beta.

STEPS TO REPRODUCE
Hover over submenus (with separators).

While it's fine on my machine after downloading, I can't seem to play the attached video directly in the browser. Let me know if this is a problem, then I will try to reencode. Thanks!

Sorry for the noise, I think I fixed the video.

Since I opened this bug, I've switched icon theme (now using breeze), the problem is even more visible. Previously I thought it had something to do with separators, but I see the same in positions where neither submenu has a separator (the top- and bottom most icons).
