<p>Hi VTK users,</p>
<p><br>
</p>
<p>I am facing a strange issue. I am using QVTKWidget in my application and it works very well on my desktop computer. The same code when I try to compile on my laptop it throws me this error message:</p>
<p><br>
</p>
<p>"Invalid pixel format, no opengl support"</p>
<p><br>
</p>
<p>I would like to know what are the scenarios in which VTK throws this message. Whether there is any dependency on various versions of Windows OS? I believe it should not be. Below is the system information where I get this error:</p>
