Post in the support area and fill in the system information.

How in the world do you navigate this thing? I followed the steps and tried to post and the information has been lost.

Hi @Carl_Alexander,

Would you kindly use the directions found here and send us over a set of logs using a shared Dropbox link so the team can take a look?


Hi @Carl_Alexander,

Thanks for sending those over. I reviewed with the team, and we’re seeing that there are errors relating to the GPU’s ability to render Roon properly.

Can you confirm the model of GPU you’re using? Does it support OpenGL 3.0?

The first thing I’d recommend trying here, assuming that OpenGL 3.0 is supported, is updating the graphics drivers and seeing if that helps.

My computer uses and AMD M880G with ATI mobility Radeon HD 4200.

I’m not sure how well AMD supports OpenGL. Furthermore, don’t know how to change a GPU. Any work around?

Hi @Carl_Alexander,

Can you try updating the graphics drivers? It looks like you can find the drivers for this GPU here.
