Like most I had no issues with the dots as they were previously, and like other have said I have not seen any feedback from others that there was an issue with the dots.
The brighter, larger dots were very noticeable on the green and relatively easy to adjust for.
When using the Chip/Pitch shot mode from the fairway the larger, brighter dots obscure the flag stick making the Chip/Pitch shot mode green grid less useful than it was before for approach shots.
It seems to be a solution to a problem that didn't exist.
FWIW- the Replay bug was not yet fixed as of last night when I played 9 on KIawah's back 9.
All in all WGT left a very poor impression (C- grade) with all the issues that were included with this latest update. It is utterly amazing the changes were not sufficiently tested, if they were in fact tested at all, before being made active for WGT's members. I suspect the people doing the testing are not sufficiently accomplished at playing WGT golf to thoroughly test updates.
