[rakesh3]

Hi team, 

I am using the imx6qsabresd board with kernel 5.10..175 and using the imx-gpu-viv version 6.4.3.

While running the qt5 application i am getting the below warning but the application is running fine seems.

libEGL warning: DRI2 failed to authenticate.

what this warning means and Does it affect my CPU performance in any way ?

Please help me to understand this warning and how to remove this warning also.

Regards,

Rk

Hi @rakesh3, 

Based on the error there could be a problem with the app performance related to the interface between GPU and the application.
However, I found some solutions that you could apply to avoid this error related to a misconfiguration of permissions to the app and system.

You could try a workaround like the following solution used at this link:
raspbian - Qt applications don't work due to libEGL - Raspberry Pi Stack Exchange

I hope this information will be helpful. 

Have a great day!
