No. I think those settings are uninvolved. I double-checked
both the setting for drop shadows on icon labels (currently
unchecked) and the Registry setting that corresponds, the
first time this happened. I've never used those drop shadows.
That's why I specifically said that
I have those settings disabled -- suspecting the obscure
performance settings would naturally be the first inclination.
This is also a sudden change that comes after the brief
monitor blackout, and clears up after rebooting. I also doubt
the display driver comes into it. As I mentioned, I have the
latest. But I also don't see any way that a funky display
driver might have a bug that changes a specific display
setting.
The short black blanking, is a VPU Recover, but as for
the rest of it, just make up an excuse :-)
Remember, I'm the guy that had dancing icons on my taskbar,
and that's traceable to some subsystem running out of RAM.
The hardware, by the way:
MSI Pro B760M-P motherboard with onboard
"Intel UHD 730" graphics.
The video card in my other machine, cost $600-$700 or so. Every
time that stupid thing starts during boot, it does not respond
properly. This seems to be a hardware bug (perhaps every identical
chip like it, does the same thing). The NVidia driver burps a few times (watchdog, and during boot), and starts OK. The Linux Nouveau driver
did not have a provision for the behavior, and I got "stuck" a
number of times. But over the years, the card today "mostly starts". Manufacturers never admit to bumbling and they're not about to
replace things like this that were released in a hurry. During
runtime there is not a problem -- it's just cold start that
has some weird issue.
You could see if the Intel site has an update for the driver.
Normally, the WU versions of drivers should be working for this.
But if you want to fiddle with it, you can try your hand.

This problem is so odd and specific that I thought maybe
someone might recognize it: Twice now, for no apparent reason,
the screen has blacked out momentarily and come back with
shadows (3D effects) on the desktop font used for labels
under icons. (Yes, I have those settings disabled.) I reboot
and it's fine again, with plain white font. No crash. No sign of
weird programs running. Though this time I start Task Manager
and briefly got a screen that said "preparing security options".
I haven't had any display problems and I've got the latest
dipsplay driver.
I've had the same problem for years. It's disconcerting when it happens,
but doesn't seem to have any ill-effects apart from putting the shadows
on the desktop icon labels, so I don't bother to reboot afterwards. It
was happening under Windows 7 as well, before I got Windows 10. My
monitor is an Acer V173 and the graphics card is an Intel HD Graphics
4400, running at 60Hz.
