pixellated block attached to cursor

Hi all, I have an annoying issue with draftsight professional. on my desktop pc the issue is not present (same license). On my laptop, I have a pixellated block attached to my crosshairs (or cursor). It changes shape in different drawings but is always present. It might be that its supposed to be text but isn't readable. Photos attached.

The block does not affact functionality but is V V annoying.

Any ideas how I can get rid of this? All contributions gratefully received.​​​​​​​
