Invisible construction lines

[7P332B5QTVW4MF]

Hello all, in my version of Fusion360 all my construction lines are invisible. See the screenshot here:

Here I drew a simple 4 with 3 straight lines. I switched the vertical line from normal to construction and it's not visible. I can still interact with it, but not easily.

This works with any curved or straight line.

Has Fusion been like this always, I've had something like that and a reboot of my computer put it right.

Rebooting removed the problem, but power cycling is never a sustainable solution.
Thank you
