QT/QML renderig - bad quality @ windows
I have a problem with QML rendering. As you can see on screen below, QML create window in bad quality. If I try to use QML animation, program will stop. It's strange because it happened only of few computers in my company. Program was tested on Windows XP, 7 and 10 and problem is on XP and 7. Program was written with QT5. It could be a OpenGL or DirectX problem?
Bad quality GUI
Here is screen from corect working program:
And here is standalone execute package of my program.
Thanks for help
@Adrian-W Hi, and welcome to the Qt forum!
This is most likely a problem with too old GPU / OpenGL driver. You can try to force your application to use DirectX by adding the following to your main.cpp:
// Options on Windows; set before instantiating QApplication QCoreApplication::setAttribute( Qt::AA_UseOpenGLES ); // use DirectX via ANGLE
Thank you for fast reply!!
This option was a point! With atribute Qt::AA_UseOpenGLES I have problem with run a program on all machines.
I read a documentation and Qt::AA_UseSoftwareOpenGL atribute solve my problem.
