QOpenGlFrameBufferObject: Framebuffer incomplete attachmentReturn to overview

Trying to increase performance on my Qt6.9 build. seems when i boot up my program, it spams me with this error:
QOpenGLFramebufferObject: Framebuffer incomplete attachment.

Any ideas what i need to do to fix this error?

Could it be related to something like this https://www.qcustomplot.com/index.php/support/forum/1204?

Nope. tried the change. still giving the errors

And actually adding that code seems to entirely break other non-qcustomplot things that use opengl

I would say from your feedback that this is likely related. Can you easily try that other "things using OpenGL" together with a QWebEngineView?
If I understand correctly each widget using OpenGL has to manage its own OpenGL context and ensure it is using the right one while painting (that's what QCP was missing).
