Accessibility zoom screen recording distortion

I saw a few other posts about this problem (from a few months ago), but I guess there's still no solution:

I use screen recording software (on High Sierra) to capture my online tutorials, and I use accessibility zoom a lot (CTRL-scroll). But, at the moment the screen get's distorted as you can see below... It doesn't matter which screen recording software you use, so I guess it's a High Sierra problem. I use Screenflow, but even QuickTime has the same problem.

One solution can be: activate the window in window mode, but that's no solution for me, because I think this mode works a bit confusing in a tutorial, and, more important: it doesn't scale the cursor...

Does someone know if there is a bug fix coming soon in a next High Sierra release? Or, is there another solution available? Thanks a lot!
