Comment 1 Martin Flöser 2019-06-15 18:01:28 UTC 
X11 or Wayland?
Comment 2 Victor Prudniy 2019-06-16 01:07:21 UTC 
x11
Comment 3 Victor Prudniy 2019-06-16 01:12:06 UTC 
Also now found that this bug appears only for windows without titlebar
Comment 4 Martin Flöser 2019-06-16 08:28:34 UTC 
On X11 this window is positioned by Qt. I doubt there's anything we can do.
Comment 5 Victor Prudniy 2019-06-16 10:51:55 UTC 
I tested on Wayland and behavior is the same. But tbh Wayland on my machine so unstable that this problem looks extremely minor.

Placement of submenus is done by Qt libraries. Please report this issue directly to Qt developers via https://bugreports.qt.io/
