Sven Co-op "green lines on screen" problem in Intel GPU

[Ame]

I have a problem with Sven for the last 5 days when I owned a new laptop, the problem is that there are green lines all over the screen and it's hard to look at. It made the game completely unplayable, I had installed all the necessary stuff on my laptop, such as DirectX and Visual C++. I'm not sure what's causing the problem either but it will be nice if there's a fix for this problem.
It's not only Sven Co-op too, it's the other GoldSrc games as well, such as CS 1.6, HL, HL Opposing Force, Blue Shift and many other GoldSrc games.

Here are the specs if you ask:
CPU: Intel Core i5-6300U 2.40GHz
GPU: Intel HD Graphics 520
RAM: 4 GB
OS: Windows 10

and here's screenshots of the problem I'm talking about.

(Thank you to the one's who helps with this problem!)

Using the "-nomtex" launch parameter may be of use:

(This is specific to Sven Co-op only if I remember correctly.)

I trust you have the latest Intel GPU drivers already? https://www.intel.com/content/www/us/en/support/detect.html

[Ame]

I did try to do -nomtex, but no luck. The screen is still broken anyway.
Yes, I do have the latest Intel GPU drivers.

About the broken screen problem, it might have to do something with the engine, I have never seen this bug.

Sven Co-op runs OpenGL, I would recommend quickly running FurMark and see if the same issue occurs https://geeks3d.com/furmark/ (Not to long as its designed to push the gfx chip hard)

[Ame]

I attempted to use FurMark and did it's benchmarks. OpenGL works fine there, no problems, but Sven Co-op is still broken.

[Analog Feelings]

Roll back drivers, had the same issue too.

[Ame]

The GPU doesn't let me Roll Back, the option is unavailable.
I don't really know what to do, other OpenGL games work just fine but not Sven Co-op.

somebody help this man im having the same problem and nobody is giving him the answers that he actually needs, it's not an fps problem it's the actual green lines.

HOW DO WE GET RID OF THEM?????

[Adambean]

Sorry but I can't help. I don't have an Intel GPU to test this with.
I'll ask others on the team if they know of anything on this.

Running SC and other GoldSrc games just peachy over here on an Intel Core i5-4570S with Intel HD Graphics 4600, and I've got to say that I've never ever encountered anything like this before. I want to say that it's the graphics card drivers that are the culprit here because as Aesthetical mentioned, reverting drivers appeared to fix the issue.

Unfortunately, I don't really know where to begin with reverting them properly though, it's a whole lengthy process which tends to be rather annoying and downright problematic due to how poorly Windows handles driver downgrading.

[Adambean]

Sometimes you need to do this kind of thing in safe mode so you can revert to a basic VGA driver.

If you are still having problems, downgrade your GPU Driver. Newer Intel igpu drivers completely break goldsrc games for some reason, so just try to get an older driver and then play.

Does completely removing the drivers and reinstalling newer drivers not work either?

I'm also having problems with this, nothing has worked for me either. It was working yesterday and today i don't know if it has anything to do with me installing a VM on my laptop or not but its frustrating because uninstalling or steams file integrity check or updating the drivers works

[Captain.Scarlet]

Are you running the vm's at the same time as running Sven Co-op?

That's an important question.

Which Hypervisor you're using matters, and whether you've delegated 3D acceleration to your guest VMs.
