I am having the same issue as above on my laptop, but not my desktop (Both the unit selector box and the unit health bars are off).
As far as I know I have never had the issues listed above with my desktop which has the following specs:
AMD Ryzen r9 3900x, gtx 1070, 32 gb of ram, 2560 x 1440 native resolution.
I am playing at 4k ultra settings for my desktop.
I am however having issues with my laptop with the listed specs:
Intel Core i7-8565U, 16 gb of ram, integrated graphics, 3840 x 2160 native resolution.
