Hi Paul,
I have done a small program pulled from my main game that shows the fault. Hopefully I have attached it correctly! It seems to be something to do with the low screen resolution I am using I think. It does not happen every time it is run, only most of the time (and only with the new Vulkan Renderer). I also noticed that on my main full game screen in my original post, that if the dots appear on the smaller lower texts, it is not on the larger upper texts, and vica-versa... Hopefully, all this will help you find the fault, unless it is something specific to only my system!
Regards
Kevin
