Resizing 3D Viewer window crashes KiCad

[Sean]

KiCad crashes immediately when attempting to resize the 3D Viewer window. Crashes after dragging to resize or hitting the maximize window button.

I can not reproduce this issue on windows nor linux. Could you try to provide some details about your graphics card?

[Sean (braveheart18)]

Sure thing.

Intel HD Graphics 520

Does this alo happen with the latest nightly?

[Nick Østergaard (nickoe)]

Does it also happen with the nigthlies?

And I was still experiencing the crash. Is there a different version I

[Mario Luzeiro (mrluzeiro)]

Are you using the latest drivers version?
Does the pcbnew on OpenGL mode works ok?

[Sean (braveheart18)]

Yes pcbnew works in OpenGL mode. I tested reading a netlist, moving some parts around and drawing a couple traces

[Wayne Stambaugh (stambaughw)]

Have you tried to duplicate this with a different project such as one of the sample projects? I cannot duplicate the failure with the head of the current 4.0 stable branch or the head of the master branch. There are no 3D viewer bug fixes in the 4.0 branch since 4.0.4 so this bug should still exist if it isn't specific to your system or your project.

[Sean (braveheart18)]

I downloaded Olinuxino and the 3d viewer still crashed after resizing the
window.

Looks like it's an issue with your intel graphics driver. I have an
older intel graphics chip that works without issues. Do have the latest
drivers installed?

Yes I have the latest drivers. I'm going to install 4.04 on an identical
machine to see if I can recreate the bug.

[Sean (braveheart18)]

Turns out I lied, I did not have the latest drivers. Updating from Device
Manager said I was up to date, but there was a new driver on lenovos
website.

Date - 10/7/16
Ver - 21.20.16.4534

And now...

3DViewer won't even start before Kicad crashes. Guess its back to the old
drivers.

[Mario Luzeiro (mrluzeiro)]

Hi Sean,

Looking for your GPU: Intel HD Graphics 520
it gives this intel webpage:
http://www.intel.com/content/www/us/en/support/graphics-drivers/graphics-for-6th-generation-intel-processors/intel-hd-graphics-520.html

with the latest drivers:
Intel Graphics Beta Driver [15.45]
Date: 02-Dec-2016 Version: Beta 15.45.12.4552 (Latest) OS: Windows 7, 64-bit*, Windows 8.1, 64-bit*, Windows® 10, 64-bit*

I dont know why this latest is 15.* and you are using 21.* versions.

If you search for "ig9icd64" on web some pages with the subject "crash" and "don't work".
I only remember to read here on KiCad issues GPU specific related with Intel GPUs :/ No other specific issues on other GPUs vendors.

If I had a computer with that GPU I could debug it, but it looks really some issue that only happen on Intel GPUs :/
KiCad 3D-Viewer is using old spec features for GPU, using a general OpenGL library without any specific vendor options. So it should work on any GPU with maybe 10's years old.

I will ask on the development list looking for someone that have that GPU to try to reproduce it.

[Sean (braveheart18)]

Hi Mario,

Before when I tried downloading directly from intel, the installer quit
because my laptop manufacturer disables generic vendor drivers from being
installed. I brute forced my way through that and installed the Beta 15.45.
Readme in the driver zip file the driver version reads 21.20.16.4552. So I
guess that is suppose to be that way. I'll try to investigate more issues
with my chipset and that DLL.

I was able to try on another computer that had the same graphics chip but a
different CPU and I could NOT reproduce the error. Looking more and more
like it might be specific to this machine.

Thanks for all your help

[Sean (braveheart18)]

I have found the culprit. A USB display adapter driver that was installed
on my machine must have been interfering somehow. I have since uninstalled
that application from my computer and 3d viewer appears to be working fine.

If you would like to try and recreate the issue. Install
http://www.displaylink.com/downloads/windows for windows 7 x64.

Thank you for all your help/suggestions.
