Getting the same thing, used to work previously but no longer does. Reinstalling didn't help. :(

Are you on the same version as the Original Poster @donnervetter, or are you running a build from master etc.?

[donnervetter]

Kap version 1.0.1 (1.0.1.170)

Just posting the error and stack track here to make it searchable. Also removing Can't reproduce since we've had multiple other reports.

Does anyone know if this only happens with multiple monitor setups? Could it be related to #141?

[dagvers]

This also happens without any external monitors hooked up to my macbook pro.

I'm looking through the aperture swift code and I'm finding some places where the error could originate from. I will send a PR to aperture with better error handling (better logging so we can see what goes wrong) and can build a custom Kap with this version (or just provide the aperture binary if you're comfortable switching it out in your Kap.app)

Just to make sure it's nothing silly, could you try switching the fps ?

[albinekb]

@sindresorhus i sent this PR to aperture, but later saw that I had based it of an outdated master.

I think we'll get better error with https://github.com/wulkano/aperture/pull/48 ?

[sindresorhus]

@dagvers @donnervetter Can you try the latest build https://kap-artifacts.now.sh/master and see if it's still an issue? There has been a lot of changes since v1.

[donnervetter]

@sindresorhus it's working! yay

[albinekb]

Awesome @donnervetter 🎉 Let's wait for @dagvers to confirm it too before closing this.
