System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: Radeon RX 560X ATI Technologies Inc. 4.5.14830 Core Profile Context 21.4.1 27.20.21002.112

Blender Version
Broken: version: 2.93.1, branch: master, commit date: 2021-06-22 05:57, hash: 1b8d33b18c

Short description of error
When I change from Viewport Solid Mode to Viewport Render Preview, I see a weird glitchy, multicolored dots, thing, and when I orbit the shape of the object becomes invisible, and the weird glitch dots move inside the invisible shape. Both Workbench and Cycles work perfectly as expected. I have already tried downgrading my Radeon drivers from 21.5.2 to 21.4.1 and the result is the same.

Exact steps for others to reproduce the error

Open attached project file or a general new file project preset
Change Viewport from Solid Mode to Render Preview
Change Render Engines from Eevee to Cycles to Workbench back to Eevee

After the AMD driver update (not sure but 21.4 onwards) , Eevee render engine has such glitches.

You can temporary fix this with Render Properties -> Performance -> High Quality Normals.

may be @Jeroen-Bakker can help you.

If setting the high quality normals fixes the issue I will be glad to add the workaround for this card and push the fix to 2.83 and 2.93. But first would need confirmation from @Daydreamingbackagain

oops, wrong action.

@Jeroen-Bakker , I translated the @nader 's comment from the task #89404. He said issue is fixed for him after setting high quality normals to true

#82856 (After updating the video card drivers to 20.11.2, interface artifacts appeared.)

@PratikPB2123 Those are two different generations. Blacklisting a card needs to be done on the actual GPU name.
Will assign this ticket to me and plat to enable the workaround next week.

Hey, thank you so much! High Quality Normals worked and now Eevee render engine works. I feel like I should add that today I went into the Shading workspace and selected Viewport Material Preview Mode and Cycles doesn't work there either, changing it back to Render Preview fixes cycles again, or "High Quality Normals". Cheers! @Jeroen-Bakker @PratikPB2123

The RX 560X was already blacklisted. So it is a bit strange that manually setting up the workaround seems like to fix it from the user.

Is it possible to upload the system info generated from blender help menu perhaps it is not an exact match with our logic.

As the user also reports that this is an eevee only issue it seems like it isn't the hq normals that would fix this as these glitches also happen in workbench.

Hi, what does it mean if my graphics card is blacklisted? Shouldn't it work? And I see that this was updated to "Needs information from user" what exactly do you need and how to get it and I'll upload/check/verify etc...

Pratik Borhade commented

what exactly do you need and how to get it

Open Blender -> Help -> Save System Info , save the generated file then attach it here (simply drag and drop)

system-info.txt
and about my graphics card being blacklisted? Does that mean I won't get future updates or something like that?

@Daydreamingbackagain Hi sorry for the confusion. I used the term blacklist before, but it is actually a whitelist

There are many different GPU/drivers/platform configuration that we support. With whitelisting a specific GPU will be enabled with a specific work-around to solve a known issue inside the driver.
Ah thanks for the info. I see the issue and we can add the card to the whitelist. Thanks!
