Hey, SESI

Since some time ago, I am getting weird viewport glitches when using wireframe display mode on my linux laptop, when running houdini on integrated Intel GPU. It looks like this:


Any ideas what's going on here?


Thanks,
Vlad

P.S. I have attached Houdini Info.txt:

What internal GPU do you have? Did it ever work before? Can you test older Houdini versions?
I can see you're running on mesa 19.0.3.

I have the same problem. I tried mesa 13,17 and 18 so far. Always with the same problem.
I also just checked Houdini 16.5, 17.0 and 17.5 of course.

Anyone here who can help? There is no option for me to install a dedicated GPU, since it's a remote machine.

It's an Intel integrated graphics, VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller. And yes, it used to work before, as I remember.

Is there any chance to find out when it worked?
Did you upgrade your drivers at some point? Switched to mesa from something else?
Is it the houdini version maybe?

So, I checked the bug(?) against the houdini installations that I have on my laptop, the earliest 17.5 I could go to was 17.5.173, which showed the same viewport glitch; I also have some beta versions that I can not run any more, so I can not tell if the bug(?) was earlier in 17.5 or not. However 17.0.352 runs fine and shows no glitch.

Could it be related to line smoothing? I see that wireframe is not smoothed in 17.0 build, on the other hand, in 17.5 builds lines are smoothed and the viewport shows glitches.
