You can use it to capture an app's OpenGL calls and replay them. You can even replay a trace made on Windows in Linux. Doing that could help determine if the artifacts are on Windows only, or on Linux too, for example.<br>
<br>
Other than that, it's a matter of debugging with visual studio or whatever tools you have. Admittedly, it could be big task if one doesn't have experience with Mesa/gallium.<br>

Hi Brian, I think the info you've provided has been helpful.<br>
<br>
What would normal course of action be to do the graphics debugging with<br>
an open source? I'm not on the dev side here but rather on the<br>
applications side, so I'm interested in giving them info on how they can<br>
look into this further.<br>
<br>
Thanks.<br>

Yes, llvmpipe should provide much better performance than the MS<br>
software driver. But llvmpipe in a Windows guest isn't a<br>
configuration that anyone really tests (including VMware), AFAIK.<br>
<br>
Sounds like solidworks is testing the OpenGL driver in some way<br>
during installation after all. The only hope of diagnosing that<br>
would probably be with 'apitrace' (on github). But it might be<br>
tricky to do.<br>
<br>
As for the rendering artifacts, it would require some general<br>
debugging effort to narrow it down.<br>
<br>
I'm afraid I can't help much more than that. I don't have any spare<br>
time and the higher-ups would probably frown on me spending time on<br>
a competing platform.<br>

Hi Brian, thanks for the feedback.<br>
<br>
We are using the mesa driver because our understanding was that<br>
it would<br>
provide better performance than a standard software opengl<br>
driver for<br>
the amazon t2 systems that we have the driver installed on.<br>
<br>
Regarding the apps, the behaviors we have seen:<br>
1. solidworks, stalls at around 75% during installation with this<br>
driver. removing it, install goes through without issue. when<br>
the driver<br>
is installed, you are able to open a model but then the app will<br>
crash<br>
after several rotations of a model. without the driver, the app<br>
works<br>
fine, just slow.<br>
2. solidedge, install is ok if i remember correctly. but with<br>
the driver<br>
installed, graphics window generally has artifacts that remain<br>
and when<br>
clicking tabs in the application, they do not highlight unless<br>
the whole<br>
app is moved around on the screen.<br>
<br>
Let me know if that adds more clarity to the situation and if<br>
you have<br>
any suggestions. Thanks!<br>
<br>

According to the screenshot, you're using the llvmpipe<br>
driver on<br>
Windows. The Mesa version is 10.something (you'd have to<br>
click on<br>
the "See details..." link to get the specific version.)<br>
<br>
The first question is, why are you using Mesa instead of a<br>
regular<br>
GPU driver? What kind of GPU do you have?<br>
<br>
Your original question/problem was:<br>
<br>
"Has anyone used the mesa drivers with CAD apps like solid<br>
edge or<br>
solidworks? We have been using them and find that the apps<br>
don't<br>
install or have issues displaying graphics properly."<br>
<br>
I guess I'd need more details. When an app doesn't<br>
install, what<br>
exactly is the installer complaining about? Some CAD apps<br>
refuse to<br>
run with "non-certified" OpenGL drivers. But that's usually an<br>
issue when the app is started, not at install time.<br>
<br>
As for display problems, again, what exactly is the issue?<br>
A few<br>
months ago, I fixed a few issues related to drawing long<br>
GL_LINE_LOOP primitives and Roland recently fixed some<br>
issues with<br>
glEdgeFlag in llvmpipe that fixes at least one CAD app<br>
(Spazio3D).<br>
I don't know of any other outstanding llvmpipe rendering<br>
issues. If<br>
something is mis-rendered, perhaps you can file a Mesa bug<br>
report<br>
with as much detail as possible.<br>
