Glitches with new AMD drivers (Adrenalin 22.7.1 or 22.8.2) when overlay has transparent images #100034

Blender Version
Broken: version: 3.2.1, branch: master, commit date: 2022-07-05 15:44, hash: a2d59b2dac
Worked: version 3.1.2 (official release), not when rebuilding it from scratch...

Short description of error
When I import some image with transparency to appear as a scene object, distorted colored lines appear as shown in the attached image.

Render view (corruption is limited to the cube):

Exact steps for others to reproduce the error

Open attached .blend file
RefImage.blend

Also happens for camera-images, but only when in back. when set to front it renders fine. For empties this is the same.

Thanks for the report. Please attach the .blend file shown in the picture.
I suspect this is same as #83022 (Transparency in Solid View Causes Glitch Artifacts)

i think this happen when i add a background image

I can confirm this. (Windows 10 / RX570 / installed latest driver 22.7.1)

Solid view:

RefImage.blend

As far as I can see:

This happens when reference image's depth setting is set to Back
It corrupts viewport overlay drawings like grid, global axes, drawings for camera and light, but transform gizmos are not affected
It doesn't matter if view is orthographic or perspective
This does not happen in 2.93 and 3.1.2 but happens in 3.2.1 and 3.3

Changed status from 'Needs User Info' to: 'Needs Triage'

Thanks for the information. Seems GPU specific issue.
I'll check again with AMD GPU. Resetting the status for now.

Added subscriber: @mano-wii

My GPU has been moved by AMD to legacy support so can't update drivers (and with old drivers this issue is not replicable)
@mano-wii, can you check with your AMD GPU: AMD Radeon RX 480

Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: AMD Radeon(TM) 535 ATI Technologies Inc. 4.5.14831 Core Profile Context 21.5.2 27.20.21003.8013```

Changed status from 'Needs Triage' to: 'Confirmed'

I can confirm the problem.
It appears to be a recent regression as the same issue is not seen on 0e9367fc29.
I'm not sure if my driver is the latest, I didn't need to update it.
Investigating...

~~It's strange, but the problem seems to be introduced in 9015952c9c.~~
~~That commit doesn't show anything suspicious.~~

Actually I got confused with the settings in the preferences. The bug is also seem in old versions

i have the same problem, with amd 6900xt

Added subscriber: @Jeroen-Bakker

Looking at the automatic recommendations of AMD driver version 22.5.1 should be used. 22.7.1 is not the preferred drivers (at least for the Vega card I am using)
When using 22.5.1 I don't have this issue.

When selecting optional driver would install 22.7.1 which shows the issue in the driver. For now I will lower the priority as stuff can fail when not using recommended drivers.

If there are recommended setups failing we could raise the issue again.

I can confirm this as well, driver 22.7.1 using an RX 5600 XT.

Did anyone try out the new drivers released today (22.8.1) to see if this issue is fixed?

Thanks for the info!

This also happens when you set view clipping region. (Confirmed with 22.7.1 and 22.8.1. Not happening in 22.5.1. So likely the same cause.)

Also I found a workaround for the time being or in case this won't be fixed for a while.

Go Preferences > Viewport > Quality > Smooth Wires and uncheck Overlay. Now corruption is limited to selection outlines. Since selection outlines are rarely shown in Edit or Sculpt mode, you probably can work with it

If you really want corruption-free viewport. You can hide selection outlines in viewport overlay settings. Gizmo-based objects (lights, camera) are fine but for meshes, it's really hard to know what's selected without outlines. Instead, turning on wireframe display can help you see that

Thanks for the great tip!

Did some more experiments today. What I did see was that the depth test was is enabled for background images (for under alpha transparency), but there was no depth buffer attached. Attaching one didn't solve the issue. Next week want to add a assert around this case to make sure that Blender warns developers to attach the correct framebuffer.

It could be that previous drivers would reused the last attached depth buffer, but recent drivers unset the depth buffer what lead to reading from uninitialized GPU memory.
Root cause hasn't been found yet.

I would like to note that blender version 2.90.1 does not have this problem.

Thanks, I hope this workaround will help tracking down the root of the issue.

This issue seems to have been fixed in the 21.11.1 driver

Indeed! From AMD's release notes :

Fixed Issues
OpenGL applications using MSAA may see visual corruption.

@Jeroen-Bakker / @mano-wii , can you also check whether this is fixed in newer AMD driver (see last two comments).

Added subscriber: @NicoleRu

Changed status from 'Confirmed' to: 'Resolved'

I can confirm the problem is fixed in driver 21.11.1
It seems like a solution so I'm closing the report.

The report can be reopened if further investigation is required.
