[1.1.2]Voxel rendering issues on system with AMD RX580

[akimmet]

I have been having voxel rendering issues on my system with a AMD RX580. I am using driver version 21.6.2.
Voxels work correctly on this system in Raze version 0.8.1, but not in 0.9.1 or newer.

On another system with a nVidia RTX 2070 Super, it can display voxels without issues running Raze 1.1.2.

Here is a small update...

I have since noticed the latest gzdoom (4.6.0) also has problems displaying voxels on this system.

Since the system that is showing this problem also has Slackware-current Linux installed, I built Raze 1.1.2 for Linux.
I had no problems what so ever using Linux. I am now certain this isn't hardware problem at all, and is probably the Windows AMD drivers doing something dumb.
If anyone else is able to reproduce this with another system, perhaps there will need to be a workaround for those of us with an AMD GPU.

What if you switch between Vulkan and OpenGL?

This is what I see with my RX 550 using Vulkan:


OpenGL looks the same, to me.

Here's my driver info:

This seems to be a classic case of a bad driver push by AMD. If you are on the latest driver, revert to an older version, and then report the problem directly to AMD themselves. There isn't much we can do on our end.

update: I just looked and 21.6.2 is the latest AMD driver version, as of this post. Please do the report and driver downgrade - this is not something Raze can control.

Thanks Rachael for showing a working example with a RX550 GPU.
I downgraded my GPU drivers to the same version depicted in your example, which turned out to be 21.4.1.
That seemed to fix things, no problem in either OpenGL or Vulkan.

The only downside is that Doom Eternal annoys me with a popup saying I need to upgrade to driver 21.6.2 every time...
