Im trying to build by own ticketer, and its working really well, however it keeps jerking and flashing. Im not quite sure why its happening as it seems random. and its working on a decent spec PC so isnt the hardware issue. I have tried Chrome, IE 11 and Firefox all seem to have the same issue.
Ive put it on jsfiddle in the hope someone can advise me :-)
Any ideas whats causing the issue, or how to fix it?
