ps: i had a chat with a mozilla developer some time ago: they never use
desktop opengl on windows, but only use ANGLE with a fallback to
software rendering, if the application crashes on customer's machines.
You can force Qt to use Angle by setting the QT_OPENGL environment
variable to QT_OPENG

This is not directly related, but that it is why I thought it was a Qt bug.
It it so easy in OpenGL to use badly API and having a good result that will
work on almost all configurations.
Dislike in Vulkan there is no way to check if APIs are correctly used, so
when we test our engine we can't real

Hi Oliver,
All other applications that crash at startup on the hardware on which we
also have the issue are made with Qt, games and all other applications are
running fine.
We finally found that it is specific to the latest Nvidia driver 381.65 and
at least geforce 1070 and 1060, we have tested on

Still a bug in nVidia code

Here is the trace.
I don't know if it is an error from the Nvidia drivers or Qt.

Ok, Thank you for suggestions Sergio, I also never used Apitrace.
The black list seems to be a good thing even if it can't work for us as for
the moment we have our homebrew 3D engine that directly call opengl.
If you have tips to migrate our engine to Angle I will be interested

Could be, but you'll have to prove it.
I suggest:
- Create a minimal-testcase which reproduces the problem
- Run apitrace on it [1] (Never used it

broken opengl drivers are a known issue on windows. it may be reasonable
to add this driver/device combination to the qt opengl blacklist and
enforce the use of
It is not necessary a bug from Nvidia, it can comes from bad parameters to

Then the bug is in NVidia code. Report to them, please.

Hi,
I think that I have found a crash in the nvidia drivers made by QtQuick.
On the computer on which our application crash at startup in the
nvoglv32.dll QtCreator crash too in the same way, that it why I suspect
that it comes from Qt.
It seems to be specific to the following configuration:
