Re: Problems with first person mode
I have tested on my iMac and cannot reproduce the issue. I do not see my mouse's 'white circle' stuck in the upper left corner. Mine seems to be right in the middle of the screen/line of view, and does seem to sync fine with the task selected on the item the circle is choosing/interacting with.
iMac (Retina 5K, 27-inch, Late 2015)
Processor: 3.2 GHz Intel Core i5
Memory: 32 GB 1867 MHz DDR3
Graphics: AMD Radeon R9 M390 2 GB
macOS 10.14.4 Mojave
Per @Bluebellflora's suggestion I re-tested with 'retina display' enabled in my game and was able to reproduce the issue, plus it sometimes creates an odd behavior of a white bar appearing as pictured (when successfully clicking on a 'go here' type area).
