I would have thought I have the codecs already installed as I can get
the Blu-ray to play in VLC now after installing everything necessary
to rectify what it said was missing,
As a point in general, different players don't all use the same codecs.
VLC was often able to play things that other's couldn't.

I have a few players installed, and for general double-clicking on some
video file to see what it is, I'll use "mpv" (a small application, it
loads just one file, with a minimal interface on the screen).  If I
want to play a stack of files in a playlist, I'll use VLC.

but playing the disc in VLC produces artifacts on the screen through
the video and vertical bars all across the border between the video
and the black bars.
Which could be as simply as a bottleneck in how fast it can stream data
to it.  You could try increasing the buffer size.  There'll be a delay
before it starts playing as it fills the buffer more than before, but
it has a larger buffer to play though any hiccups.

It could also be that something else is taxing your system, and VLC is
having to wait for its turn too much.

The other thing I've noticed is if I run Kodi windowed instead of
fullscreen it starts with its window sized to the physical dimensions
of the monitor (4K) and when it hangs I can't use ctrl+tab to switch
to windows behind it and the mouse point won't move, but if I run say
konsole half screen and Kodi half screen when Kodi hangs I can get to
the konsole window to kill Kodi.
Such hangs could be a video card issue (drivers for it, the card itself
[faults, cooling], or that the card need re-seating in the motherboard
socket).  Or how the graphic card is made available to the emulator.

I'm only trying Kodi because I found a net article that said Kodi
could play Bu-ray movies. What I haven't done yet is install and try
Kodi under windows, but under windows the version of Laewo that
struggles with playing the Blu-ray under Wine plays the same Blu-rays
without any issue at all using the same USB Blu-ray device.
Running an application directly is Linux ought to give it the best
chance at working properly.  Running Windows programs through an
emulator brings a set of baggage with it.  How compatible is it, how
well does the emulator support it?  Can the emulator run quick enough?
Is there a bottleneck in passing data through into the emulator and out
again?  How well is graphics supported?  Does the emulator get direct
access to an optical disc, or does it pass through Linux and then get
piped into the emulator?

Personally I haven't run emulators for eons.  I moved to Linux to get
away from other OSs, entirely.
I am trying to be able to play my commercial blu-ray discs on my desktop machine irrespective of whether I boot into Windows or Linux. As I had used VLC in the past under both OS's I installed it again under F43 and Windows. Under Linux it failed to run because of lack of aac audio support which I rectified and then it complained about other things which I also rectified by installing the appropriate packages, which is then when I got the video issues on playback. Under Windows I got the same failures as I did under Linux but I didn't bother trying to resolve those. Instead I did a search for Blu-ray players and found Laewo which was specified as not requiring any additional software in order to play Blu-rays, and on installation it actually did what was specified and it played them very well. As there was no Linux version the only method I could find was to install and use Laewo under wine, but under wine it has what I believe to be buffering issues. This was the reason I tried Kodi, which is a native Linux app, but as raised in this thread Kodi has issues on auto mounting the discs, both Blu-ray and DVD. I don't know if it is significant but the only way I could find documented on how to install Kodi was to install it via Flatpak, which is what I have done.
