success! I had another texture problem with my WW1 flight sim, and an idea posted there worked for this (oddly, not for the flight sim issue). in case anyone in the future needs it, VonS directed me to do the following thorough removal fo the AMD software and install only the driver, and not the extra "Adrenaline" stuff. after doing a-d below with no luck, option (e) is what worked here.
a) version of drivers 20.2.1 and above supposedly fix the problem (for the relevant AMD GPU)
b) turn off GPU (hardware) acceleration option in Discord, Chrome, and any other programs where you have GPU acceleration turned on, on your computer, and reboot for it to be turned off
c) remove registry keys for previous video card and then re-install the control panel and drivers for your latest AMD vid. card
d) set RAM speed from 2400 to 3000 MHz
e) this option taken from the internet is a more detailed one, to fix crashes on the 5600xt card, but might work also for other anomalies - always read directions carefully before attempting any of this ----->

1. uninstall radeon software (if freezes or has error dont worry goto 2)
2. run amd clean up utility (if freezes or has error dont worry goto 3)
3. boot windows into safe mode with networking (hold shift while clicking reboot in windows)
4. download and install display driver uninstaller
5. uninstall all gpu stuff and chipset stuff , using ddu , (display driver uninstaller)
6. reboot
7. check device manager, make sure display adapter says generic device, if not repeat steps 1 - 6
8. download amd chipset drivers directly from amd, selecting the appropriate categories (for AMD CPU users,,,, (((i would imagine the same would hold true for intel cpus),
( i didnt use ones from my mobo manufacturer)
9. install the latest correct chipset drivers only from amd, (intel for blue team) ( NO ADRENALIN OR GPU STUFF FROM AMD)
10. reboot
11. download adrenalin, unpack it, (( it will show a generic unzip progress bar, let it finish, when the fancy splash screen comes up that say "do you want to install adrenalin" "CLICK CLOSE / NO ****** DO NOT INSTALL ADRENALIN OR ANY AMD GPU SOFTWARE **** we are just unpacking it to get to the drivers
12. goto device manager right click on generic display driver, hit update driver
> select "browse my computer for driver software"
> choose "let me pick from a list......"
> choose "have disk"
> goto the folder that adrenalin unpacked to ussually c:\amd , im not sure what subfolder it is in, i think one that says adrenalin, either way locate C0353065.inf (i beleive there was a driver subfolder and like a win32 / win64 etc folders, choose the one appropriate for your system) (this may differ slightly for diff versions in the future) click ok, choose the top 5600 xt driver, click next,
13. (this should install the driver without adrenalin, device manager should now say "5600 xt" under display adapters)
>>>>>>>>>>> reboot
