Bug Description
I'm running Stretch, with Desktop on a new Pi 3B+ :
> OS Version:March 2018
> Release date:2018-03-13
> Kernel version:4.9
> Up-to-date as of 13:30 GMT 17/03/18
System logs are full of repeating messages, now every second as below. After extended use browsing via Chromium/ using Terminal I keep getting lock-ups on the Pi 3B+ that mean I have to hard reset.
No additional software installed, other than that available via apt-get update/ apt-get dist-upgrade.
Other (potentially?) relevant information:
> Pi is connected to Internet via wireless 5Ghz
> Using a wireless keyboard/ USB RF dongle, however errors persist every second even when I remove the USB dongle
> Using a Bluetooth mouse (see below)
> Disabling Bluetooth makes no difference

I've established that this is being caused by OpenGL being enabled - I had enabled this in "G1 GL (Full KMS)" mode. When running in "G3 Legacy" I do not get these events in the syslog.
