Rendering pane flashing

[dpmccabe]

Upgraded to 0.7.2 today and the rendering pane is flashing on almost every keypress:

It seems to happen with every combination of themes and syntax highlighting I've tried.

I have this same issue, somewhat renders the app unusable.

[akauppi]

Me too. macOS 10.15.1 on Mac Mini 2018. The precise build is 1008.

Happens regardless of macOS dark/light mode, or MacDown themes.

When I tried 0.7.2 on macOS 10.14.6 I saw the same flashing, so I don't think this is Catalina-specific.

This is not Catalina specific; I haven't installed yet and I see the same blinking. I re-installed the previous version for now.

Yes, same flickering issue with MacDown 0.7.2 on MacOS 10.14.6. I’m rolling back to the previous version 0.7.1 too.

@FranklinYu, any guesstimate as when this will be fixed?

[FranklinYu]

@jenstroeger I haven't found the cause so I cannot provide any estimate. Sorry.

@FranklinYu no problem; the app is great as it is :D; I think there's no problem waiting a little bit more for all the new features.
