I use the uBar launcher, and have noticed a weird behavior since updating Brave recently: Brave windows that are closed appear in uBar’s active windows list as if they were still open.
Closing Brave and re-opening it gets rid of any current “phantom” windows in the open windows list, but they accumulate again as more windows are opened.
This may be a glitch with uBar, but I have not seen the glitch occur with any application other than Brave, and have only seen it since recently updating Brave - so I thought I’d mention it here. (I did also report the behavior to Brawer software, who make uBar).
Just FYI, in case it helps.
