Vanman,
I had a phone conversation/web meeting with a rep from Hexagon today about this same issue. They are aware of the issue and video'd our meeting, he will be submitting to development for their input. He did mention that another OE hotfix should be coming out soon. They are also working on an SP3 for 2019 but did not feel like the visual style issue would be in that fix. The SP2 was supposed to fix the lag while in 2dwireframe but could have messed up the other visual styles while doing so. Thank you for your input though.
