@MarkWhitwell

That's not much information.
How was your app released? Architecture issue?! Screen resolution issue (high dpi)?!
(I'm just guessing)

@Pl45m4 Hi i am using Surface Pro 7+ and i using Qt5.4.1 Opengl

when i check my log i found out that it seems has some issue in QOpenGL as i am getting following warnings:

QOpenGLShaderProgram: could not create shader program
QOpenGLShader: could not create shader
QOpenGLShader: could not create shader
shader compilation failed: ""

any suggestion for me?

@MarkWhitwell have you tried googling these errors? If so, what solutions have you tried and did not work?

MarkWhitwell

@Abderrahmene_Rayene yes i have looked and found this thread https://forum.qt.io/topic/52625/qopenglshaderprogram-could-not-create-shader-program/8?_=1681473494310

As mentioned in this thread i am planning to check use DirectX via ANGLE but i am not sure if this will work

QCoreApplication::setAttribute( Qt::AA_UseOpenGLES );

do you have any better suggestion than this please let me know
