Hi Dima, that's second issue reported to the same application. https://bugs.freedesktop.org/show_bug.cgi?id=106158 here is first one. Could you please provide your model, used in the app? I didn't face with it before, so, created file will speed up my tries to reproduce the issue.
Thank you in advance.

The ring.stl file model for Simplify3D

hi Denis,

Sure, attached model here.

This crash happens quite often within this application (Simplify3D), sometimes I even have nothing to do - just slice model (this happens when I click "Prepare to print" button) and the crash happens.

And, the model itself I attached does not causes crash - I was getting it with other models as well.

I was using the latest Simplify3D version for Linux.

What other information do you need ?

Thanks,
Dima

How to avoid crashing

Uncheck checkbox "Build plate" shown on the image to avoid crashing.

We figured out that patch https://patchwork.freedesktop.org/patch/225172/ fixes this bug.

Hi Dima. Could you please apply that patch and check?
I made about 15 tries with it, and didn't get any hangs.

hi Denis,

So, I've downloaded Mesa, compiled master branch (firstly without your patch), then loaded compiled libs by using LIBGL_DRIVERS_PATH variable to specify path to compiled mesa libs, and assured that application Simplify3D works and creates "crash" in dri/mesa (?) system.

Then I applied patch, compiled mesa, and run Simplify3D with patched libs -- I didn't notice the crash this time.

I did such testing (with patched and not-patched libs) few times to get sure patch works.

Seems like it works ! Thank you so much !

If you need me to do some other testing, or some information - let me know.

Dima

Hi again, Dima. Good news, patch was accepted and added to mesa-master. I think, issue can be closed as fixed.
