Text blinking

Ugh, this is frustrating. I contacted support and got a list of things to do:

May I know if you happen to have gone through this article to ensure you followed the standard recommendations when working with Storyline 360 on a Mac with Parallels: https://articulate.com/support/article/using-articulate-software-on-a-mac-with-parallels-desktop

Most cases with issues like this are environment-related issues like outdated graphics driver or they’re running an older OS version which does not utilize DirectX 11 in the Guest OS.

Is the 16GB of RAM you mentioned, the allocated RAM for the virtual machine? Or is that the overall RAM you have in your Macbook? If ever you’ve only allocated 2GB of RAM to the virtual machine, try increasing it and see if the problem gets fixed.

Also, in Parallels 16 there is some improved support for graphics in macOS 10.14 Mojave and later. So, in case you’re running an older macOS version, I’d like to recommend you get an update if possible.

So far I've done pretty much everything on the linked page and still have blinking text. Now I am updating my High Sierra to Catalina. Here are my specs (obvi will be Catalina in about 30 minutes...)

I am running the trial and am in the middle of classes that use Articulate. I have my work saved on my drive, so I am not really worried about that. But I am worried that somehow I will not be able to reinstall my Articulate trial (which I haven't done yet, but am supposed to have done, I just learned, after disconnecting the shared folders.

SIGH. Maybe I will have to break down and buy a PC for this career. Please someone talk me down from that ledge and tell me that Mac/Catalina/Parallels CAN work smoothly and FAST (because it's also really slow, too).
