Preview window is blank.

Open modar-k opened this issue 3 years ago • 6 comments

I’m using Lookin on macOS Catalina with an iOS 14 device. The preview (middle) window inside Lookin app seems to be blank. However, when I hover over that window, different elements in the side (left) bar are highlighted which I suppose means the preview is there, but for some reason not showing.

After turning the preview from 3D to 2D, is the preview image still blank?

Yes, unfortunately. I tried to use Lookin with both the demo app, and a 3rd party app using LookinLoader on a jailbroken iPhone.. same result.

You mean you can reproduce this bug even with the demo app? It seems like a bug I’ve never heard before, and I can’t figure out possible reason for the moment.  Is this the first time you use Lookin on your computer?

Yes, it’s my first time using it. After encountering this issue I decided to give “Reveal” a try. Surprisingly, I had the same issue in Reveal!

I guess then the problem could be iPhone/macOS related.

I have the same problem.When I switched 2D to 3D or 3D to 2D,the preview was shown for a moment about 0.2second and disappeared later soon.
When I clicked the reload button, I saw the log below "[Unknown process name] CGAffineTransformInvert: singular matrix."
