Looks that way, but my red artifacts in QuickLook panes persist.
And a new bug: Three-finger tap to call up Dictionary used to work if my cursor was hovered over a word, but it now requires the word to be selected first.
Quite honestly, I'm very seriously thinking of reverting to Catalina, which I can accomplish fairly easily by updating the bootable clone I saved when I upgraded to Big Sur.
As far as I"m now concerned, BS is BS! There's not a single aspect of Big Sur that I'll miss if I revert, and several that I"ll be happy to see gone.
