I noticed my split taskbars looking dimmer individually over time. If I click the taskbar, it goes back to full brightness. Turns out, it's due to window shadows and as I have more windows in the split, the culmulative shadows make the taskbar darker.

When I drag a window over the taskbar, it shows over the taskbar, meaning the taskbar is not on top. Is this expected? For now, I've disabled window shadows to fix this.
