EQ graphic update issue

The waveform of the EQ setting disappears during switching of EQ windows.
It ios necessary to move the mouse over the window to update the graphics.

Steps to reproduce:
-set a filter
-switch the window mode on the right top corner of the EQ window. do not move the mouse
-on switching, the EQ waves disapper
-move the mouse inside the graphical EQ window. they suddenly appear


Today I noticed this same problem. Hope this will be fixed.

Also I managed to get my mixer to lose those eq curves just pressing F3 (open/close mixer). Curves comes back only hooverin mouse inside the graphical EQ window.

I try tomorrow to find something new about this problem.
