I'm really happy that VLC Player will be Universal (x86 / ARM) in the next few days. It is a player that far surpasses QuickTime (which, unfortunately, I find very uncomfortable).
Fortunately it works as always on the technical side, but ... unfortunately on the graphic side, it has some problems with Big Sur (certainly due to the interface change).
Even the counters go out of the selection range.
Hopefully at the launch of a modern VCL version in line with the new macOS layout (transparency, darkmode).
I also hope for icon adaptation ...
Currently it looks like this:
Hopefully it will be resumed with style from the one in use on iOS.
Obviously I apologize to the developers, on the technical side I have absolutely nothing to say as there is a real work of support and compatibility that I admire, but I am really sorry to have to see a technical masterpiece unfortunately hidden by an obsolete graphics.
