Yes. Sorry for being imprecise, but for this particular issue #4 the actual change I made (to work around this issue) was made in the KDE Plasma 'System Settings / Power Management' area.
There is a section labeled "Display and Brightness". I changed the settings for "Dim automatically" and "Turn off screen".
I changed these to 'Never' and that seems to have improved this specific issue (although other display quirkiness remains).
P.S.- Playing with these settings a little more seems to show that the 'Turn off screen' part was what was prompted the issue.

Hi gbhon,
Thank you for all the feedback on Fedora 41 / WS 17.5.2 on Windows.
Re (4), do I understand you right that once you set the screen to not dim/powersave, the issue goes away?
Regards,
Martin

Subject: Fedora 41 sound (and video) problems
So just an update for anyone having issues with a Fedora 41 guest and Workstation (17.5.2 under Windows 11 23H2).
Here's what I have been able to work around. This is using KDE Plasma as the desktop in my case, but some of the issues aren't related to the specific desktop being used.
1) Sound- I originally had unusable sound. I did the previously mentioned 'sudo dnf swap ...' to get things working.
But I discovered I could put the packages back to the way they originally were and update the 'alsa' values for
api.alsa.period-size = 1024
api.alsa.headroom = 8192
and it also seems to work for my setup.
2) The mesa-dri-drivers package update to 24.3.4 fixed some issues.
3) Currently I still sometimes have to leave full-screen and come back to 'unstick' the guest display. Such as
right before the log-in panel is presented on initial boot.
4) I had an issue with the screen going black and not wanting to come back unless I sent a C-A-D to the
guest. This was indeed 'screen lock' related for most of the cases. I set to never dim the screen and this doesn't
seem to be an issue for that case anyway.
5) I still see an issue where (when the guest is in full-screen), if I bring the mouse up to cause the Workstation panel
to lower, the cursor flickers as I move it and I sometimes have my mouse stuck to the upper left of the host screen when
I hit minimize (to get back to the Host desktop).
I can work around this by hitting Ctl-Shift first (to release the mouse etc.). That also works to "un-peg"
the mouse if I didn't hit it first before hitting minimize and the mouse has become has become stuck
in the upper left corner on the Host screen.
This seems to be an issue with the KDE Plasma desktop and not the Gnome desktop for some reason.

Hi gbohn,
The fix for the Mesa issue should be in Mesa 24.3.4, but unless you can afford to build that yourself, you will need to wait for Fedora to upgrade its Mesa package.
Re Fedora getting a black screen after a while, one possible cause could be the screen saver -> screen blanker kicking in, while the VM has lost kbd/mouse focus. It may take returning focus, e.g. by a mouse click over the VM desktop, *and* pressing something on the kbd, repeatedly if needed, for the desktop to wake up. If that does not help, try ssh-ing into the VM and observing the VM state from the terminal -- excessive CPU loads (top), critical events in the kernel log (sudo dmesg), the state of the shell (journalctl -b, then search for gnome messages).
Regards,
Martin

I made some progress for the moment at least on the audio issue.
Performing
sudo dnf swap --allowerasing pipewire-pulseaudio pulseaudio
sudo dnf swap wireplumber pipewire-media-session
has had the effect of fixing the sound at the moment.
I'm only guessing this uses an older package to do the sound.
In the meantime I discovered so many bad things about trying to run a Fedora 41 guest under Windows. Including
*) With the Host hypervisor running full-screen, trying to switch in and out of the Guest often results
in my mouse flickering in the Host VMWare workstation bar at the top, and frequently results
in my mouse on the host getting stuck in the upper left corner of the Host screen when switching away for no obvious reason.
*) If I leave the Fedora Guest running and go to another Guest or the host for a while, switching back to
the Fedora 41 Guest shows an all black screen I can't seem to clear up.
Sigh... In contrast, RHEL 8.10 as a guest seems to work fairly well on the same system.

I created a fresh Fedora 41 Guest (on a Windows 11 23H2 host using Workstation 17.5.2), and many things seem broken.
I had to down-level the mesa-dri-drivers package since the updated version prevented GUI things from running at all (thanks to the "techogeezer" post on the subject or I wouldn't have known about it).
I still can't run with 3D enabled, but worse than that the sound seems totally broken. It's extremely halting/choppy at best.
Is this a known issue? For comparison, on the same system a RHEL 8.10 Guest seems to work with proper sound and 3D acceleration.
I also get strange video artifacts sometimes in the guest, but I wasn't sure if that was related to the down-level mesa-dri-drivers or not.
Thanks.
