Thanks @srirambv I can reproduce with Nightly too.

Here’s the problem:

$ xprop WM_CLASS  # dev
WM_CLASS(STRING) = "brave-browser-dev", "Brave-browser-dev"
$ xprop WM_CLASS  # stable
WM_CLASS(STRING) = "brave-browser", "Brave-browser"
$ xprop WM_CLASS  # nightly
WM_CLASS(STRING) = "brave-browser", "Brave-browser"
