Thank you very much ,
I have just installed new driver gpu and try to my project. Exactly, the problem releates to openGL, my project is worked normally

Hi
Could be the openGl.
QML needs working accelerated graphics.

Did you install openGl / newest drivers for your gfx card ?

@mrjj thank you
maybe i need to install driver for gpu. Currently, I am using nvidia quandro 2000m

Hi
well it should have openGL 4.6
so yes, try go to nvidia site and find the driver.
(or from laptop vendor)

I used
https://www.nvidia.com/Download/driverResults.aspx/160350/en-us
for a Dell laptop and it worked but i cant promise it will on your system :)

Kudos! Clearly this was resolved and with the ideal method.

I just want to give a "shout out" to the excellent VirtualGL project. It has allowed me to run QML programs in instances where they otherwise would not. (On Linux, often in conjunction with Xephyr.)

The screenshots on this thread indicate Microsoft Windows. Apparently VirtualGL has a Cygwin exe release now. Just pointing this out in case others are struggling with OpenGL. (I have not tried VirtuaGL on Windows. But I love it on Linux.)
