Problem with DWMBlurGlass and StartisBack Start Menu

[WiseDrow]

Describe the bug

Whenever I close the Start Menu with a submenu of a frequent program (e.g. Word, Notepad) expanded. The blur effect is still appearing where the submenu was whenever I reopen the start menu.

To Reproduce

Open the Start Menu, leave it on a program with a submenu
Click off the Start Menu without closing the submenu.
Reopen the Start Menu
The blur will show up where the expanded menu was.

Screenshot of bug in action

It goes away when I reopen the start menu, expand a program to get the submenu and then close the submenu so it's not expanded, then close the start menu.

Additional context

Disabling 'Override AccentBlur Effect' or Changing the Blur method to something other than CustomBlur seems to fix the problem, but I lose the gloss-like effect on the taskbar (File explorer and all that still have the gloss effect).
