To progress I have decided to try new mesa compilations.
First at all, as i Have a mixed mesa version (but working) on the computer, so i want not touch my installed Mint.
As I don't know if the testing under virtual machine make sense for graphics (it's emulated how?), I have decided to test latest Ubuntu Focal Fossa 2004 on Usb stick.
The kernel is 5.4.0.9 and mesa 19.3.3
First thing: The live don't reserve enough memory to upgrade, shame i had 8 Gigs … can't add oibaf ppa...
Second : ppa:team-xbmc/ppa don't work with fossa !!
Last: the snap package coming with ubuntu software is ok with install but nothing at lunch …
So still no test, if someone have a idea how to proceed ...

I've found the issue!! A NEW AMD bug !!! not related to mesa:
I had a look in dmesg and found the message : failed initializing UVD (-1).
This is related to linux-firmware that (was) at automatic update.
I revert from 1.173.15 to 1.173 and now new kodi 18.6 works with vaapi.
At now, I have blocked updates for mesa (until it is not corrected at Ubuntu's repo) and linux-firmware.
Shame on AMD and there POOR legacy and middle old graphics cards.

Did you fully cold power cycle your machine after the linux-firmware upgrade? Some hardware can't handle a firmware update without a cold power cycle. For one of my Intel Bluetooth cards, I have to power the machine off and unplug it for a minute, then plug it back in to get it to take a new firmware. Try upgrading the firmware and doing that.
