Hi Jes89,
This may be the same behaviour as this post: https://community.allen-heath.com/forums/topic/v1-5-bug-found
As Keith said in that post:
Hi all,
Thank you to those of you who contacted us with details about this bug.
It does look scary, but only affects the output (display) of the touchscreen.
The audio, surface control and remote apps (SQ-MixPad and SQ4You) will all continue to function correctly.
The touchscreen still even works for touch.
We have now managed to reproduce it, and are currently working to get a fix out to you as soon as possible.
Thank you for bearing with us on this one!
Keith.
Thanks!
Alex
