problem in qt5 example #43

Closed AdrianSchuetz closed 6 years ago

Hi,

I have run into a weird problem trying out the examples provided by you. Running an example always gives the error message attached.

Traceback (most recent call last): File "C:\Users\VRLab\Anaconda3\lib\site-packages\openvr\glframework\qt5_app.py", line 52, in render_vr self.paintGL() File "C:\Users\VRLab\Anaconda3\lib\site-packages\openvr\glframework\qt5_app.py", line 47, in paintGL self.renderer.render_scene() File "C:\Users\VRLab\Anaconda3\lib\site-packages\openvr\gl_renderer.py", line 204, in render_scene glBindFramebuffer(GL_FRAMEBUFFER, self.right_fb.fb) File "C:\Users\VRLab\Anaconda3\lib\site-packages\OpenGL\error.py", line 232, in glCheckError baseOperation = baseOperation, OpenGL.error.GLError: GLError( err = 1282, description = b'invalid operation',

baseOperation = glBindFramebuffer, cArguments = (GL_FRAMEBUFFER, 3) )

However, some such as wx dont mind the error whereas qt5 just refuses to work. I also attached the system information. If I run the example script line by line the error does not occur.

Hello, I'm having the same issue. Did you find a workaround ?

Hi, the latest NVIDIA driver update fixed the problem for me. Now everything runs smooth.

I just had this same problem myself. Even though I already had the latest nvidia drivers (397.31). The problem resolved for me after I rebooted the computer, updated Steam and SteamVR, then power cycled the Vive controller box. I'm unsure which of those steps are necessary, except that power cycling that box at the end was required to bring my trackers back to life.
