1- open unity hub, click on projects from left
2- right click on your project(or 3dots on right side) and select “Add command line args”
3- copy and paste this:
-force-vulkan
4- select save and open your project. that’s it.

The editor crashes soon after it starts in my case; running on Iris XE Graphics, no dedicated card. Should I switch editor version?

Have you tried upgrading the graphics driver version?

@afshin_a_1

last but not least unity should care more about linux, because many of developers consider using linux. nowdays even amateur users are using linux thanks to ubuntu and it’s community is going bigger and bigger.

i think It makes more sense using linux than windows as a developer point of view, since cross-platform windows/linux/mac is guaranteed to work well when you develop on linux, so this includes Valve’s new console and multiplayer servers. besides, the best ide for C# right now is rider, so you’re not losing anything.

Try with the latest 2021.3 LTS. I didn’t have this problem with opengl when I used 2021.3.27f1.

In my case it didn’t make a difference. Using the latest nvidia 535.

Just for the record, forcing vulkan worked for me.

If it’s (confirmed to be) a driver issue related to OpenGL, you can report this to Nvidia (your GPU vendor) and they might fix this.

Anyway, I suggest switching to Vulkan if possible because AFAIK URP + OpenGL doesn’t support:

• Deferred rendering path
• Rendering Layers (Light + Decal Layers)
• Decals
• Other modern graphics features

I didn’t know that. Thank you!

Forcing Vulkan instead of OpenGL worked for me too ! Thanks for the workaround

I am experiencing the same problems as the OP. I am encountering the same red artifacts in the scene view while using the Universal Render Pipeline (URP). I am also facing the issue of a grey triangle appearing across the screen, but this only occurs when scrolling webpages through any browser, not so much noticeable in Unity.

I have attempted various solutions, including using Unity versions ranging from 2022.3.x to 2023.1.10f1. I have also updated my drivers, launched the program with the “-force-vulkan” command, and tried nearly all the suggestions mentioned in this discussion thread.

Still experiencing the same issue on 2022.3.x when using URP. This does not occur on default renderer. Switching to vulkan fixes the corrupted red dots issue, however whenever you select an object on edit scene, the editor crashes, so using URP becomes pretty much unusable.

[yassine14]

Still an issue with unity 6.

[Asten-Valentinus]

I’ve found this problem as well. Because Vulkan doesn’t currently work in Unity with dual-gpu, I’ve decided to just use the built-in renderer for now (until I need URP, or the issue is fixed.)

This is disappointing, as there are so many advantages with URP!

[meta11co]

Still the same problem. Forcing Vulkan worked for me.

[Asten-Valentinus]

Recently switched over to URP again after updates.

Seems to be fixed on Unity 6, though Vulkan is still broken for dual-gpu.

[Junacik99]

I just installed Unity 6 on Ubuntu 20. “Red dots” problem is still present. I had to switch from URP to default render

[valentinwinkelmann]

This issue still exists on Unity 6000.1.1f1 on Ubuntu 24.04.2 LTS. The -force-vulkan seams to fix it.

[s300mehran]

Go to Edit → Project Settings → Player → Windows, Mac and Linux (The little desktop icon) → Other Settings.
Then disable Auto Graphics API for linux.
After that, move “Vulcan” to the top.
Restart the editor.
It worked for me and hopefully it works for you too.

A similar issue is below:

Unity Editor Window Flickering when rendering shaded scenes | Linux Xubuntu

I get that issue as well. Your suggestion didn’t fix it @rosaParuvm I get an extra issue where my scene tab is full of weird red “particles”. I believe it’s because I’m using URP, but it’s just a template project, so I didn’t really add/remove anything. It works fine without URP, but this makes it effectively unusable for me on Linux, defeating the whole point. [8942766--1226856--Screenshot from 2023-04-12 09-03-12.png]

Hi all,

I’ve been reading a little on this issue as it’s stopping me from using an aging laptop running Linux Mint. I am unable to use Vulkan on this device, so switching APIs is not an acceptable fix for this device, and URP at this point is a necessity for its performance improvements.

This is not a fix for the half-triangle, but the red noise only occurs with Post-Processing and Skybox enabled (Scene View only). If you are able to disable these two effects in the drop-down (top-right of scene view; two stacked layers with a star), you will be able to use the Scene view as intended and the Game View is unaffected. I do hope it gets fixed eventually but OpenGL is old news and I’ll just be grateful it hasn’t been removed altogether.

Tested with 6000.1.17f1, Default URP 3D template.
