Slow 2d graphics rendering

[Jamier]

I've have a graphical app that seems to render screens slowly. After pressing the screen, it often takes a noticeable amount of time to update maybe 50 or 100ms. 

On start up of the app I see an error message "GDK is not able to create a GL context, falling back to glReadPixels (slow!): No GL implementation is available"

A search suggests this could be because hardware acceleration isn't enabled.

Does anyone know how I can check if hardware acceleration is enabled? Or if I might be missing some Yocto package that should be included?

Thanks.

Thanks for responding.

We are using Yocto Kirkstone. I looked for more log info but couldn't find anything more. I can't share the app, sorry.

I was hoping someone else might have seen this and addressed it and could share what they have done.

I did recently succeed in setting weston to use gl as renderer but this didn't make the message go away.

i.MX8QM  Linux BSP default GPU is enabled,  so it should be customer's application problem.

Which BSP version  customer using?

Any full log of this problem? 

Could customer share that app?
