An extra bar shows up at the bottom of fullscreen obsidian when I enables translucent window

Things I have tried

When both the two conditions below are satisfied, an extra translucent bar shows up at the bottom of obsidian on my Windows PC:

  • Obsidian window is fullscreen
  • Translucent window is enabled

This is a screenshot of the bar:
The bar in obsidian

This bar overlays the windows taskbar. It looks like the translucent mask is a little bit too large and out of normal area.

Change the light/dark mode or the theme(e.g. Minimal) does not fix the problem.

What I’m trying to do

I want to know whether it is normal. If not, is it something wrong with my PC or a bug of obsidian? What shall I do to fix it.
