As a workaround I switched back to the builtin dark theme.

Comment 2

[Andrei Petcu]

I managed to reproduce it with the Dark theme also. I think it happens either due to the large number of tabs or due to me using Ctrl+Tab to switch tabs. The dark theme issue seems to happen only when I have a lot of tabs while the Dream of Waves theme happens almost every time I switch tabs.

It's happening for me as well. I'm using the Quantum Lights dynamic theme. Just moving my mouse over the awesome bar or tabs is enough to hit it.

I'm on Nightly 61.0a1 (2018-03-23) (64-bit) on macOS 10.13.3 (17D102).

maybe duplication of Bug 1448301

It's happening as well to me, with all the default themes.
I could workaround it by enabling the title bar.

Nightly 61.0a1 (2018-03-23) (64-bit) on Windows 7 Pro.

Seems to be fixed for me. Closing now, will reopen if it pops up again.
