glPushClientAttrib / glPopClientAttrib do not work with FirePro W5100 / Barco MXRT-5600

I am using Qt Quick as software GUI.

Qt Quick over 5 requires unpack alignment to be 4 for correct GUI rendering.

With FirePro W5100 / Barco MXRT-5600's current driver (and previous ones), the glPushClientAttrib / glPopClientAttrib are not working (Do not have this problem with other graphics cards like NVIDIA's).

So once I changed the unpack alignment between glPushClientAttrib / glPopClientAttrib, Qt Quick GUI can no longer be rendered correctly. I have to manually change the alignment back to 4.

I wonder if there is some settings I did not do to make glPushClientAttrib / glPopClientAttrib work with these drivers.

OS: Windows 7

Qt: 5.7

When I was using Qt 4.8, it works properly. Since Qt 4.8 does not have the alignment requirement.


Thank you for your time!
