Artefacts on screen when mouse is moving. What is the problem?

Vladimir Sazonov

I use the latest version of am335x SDK. I run my QT application or QT applications from Matrix GUI on Beaglebone Black I have artefacts on display when mouse is moving. When mouse not connected all is ok. I also noticed that the led indicator of CPU activity is shines much brighter during the cursor is moving. I also do not sure that SGX in the CPU is used. The utility "System Information" from "Matrix GUI" says "SGX Core version: Unknown or not present". It is strange because in SDK release notes says that SGX is used. What is the problem?

Hi Vladimir,

There are various possible reasons which could causing artefacts. Some of them are overheating, overloaded CPU, memory corruption or some software issue. Could you check CPU temperature and CPU load when artefacts are observed. Also could you attach 'dmesg' kernel log.

Hello, Tsvetolin!
