Hello, I had to recently replace my AMD R390 card and decided to go w/ a new PowerColor Red Dragon RX5600XT.
Using the Radeon Adrenaline 20.2.2 drivers I am seeing graphic corruption in Links 2003 as shown in the attachment. The checkerbox corruption effect occurs on the foreground 3D player and additional corruption happens elsewhere onscreen, and the ball does not show on the overhead sub-view when hit.
Normally on this old game I have to override the anti-aliasing and choose 8XEQ and Supersampling to get the most detail out of it.
Unfortunately no combo of options works.
Links 2003 is using the last .exe patch from this location:
--
Visual Pinball X (I'll create a new thread for this: [Bug] Graphic corruption/artifacts in Visual Pinball X (5600XT 20.2.2) )
Am also seeing graphic drop outs with Visual Pinball X when you load a table into the editor and hit F6 to adjust the table's height and viewing angle. The table is completely missing. If you load it up with F5 to *play* it though it is there. Very odd.
Notice also in the picture a few replies below that the anti-aliasing creates the weird 'blocks' on a pinball table too, on the flippers and launch lane.
Anyhow, these are two datapoints for this new card and new drivers. The R390 doesn't have these issues w/ the 20.2.1 drivers of course. 
I submitted a bug report at https://www.amdsurveys.com/se/5A1E27D23A3DE966.
Is there another place I should submit to get AMD's attention? Thanks!

I saw in another thread https://community.amd.com/message/2960733?commentID=2960733#comment-2960733 that this may be related to older DX9 games not taking AA or AF (maybe more) overrides, which these two are, I believe.
