Severe lag with OS X client when application is running on Retina Display

[frdmn]

Your Rocket.Chat version: just recloned from master

I am using a Cinema Display in addition to my MacBook Pro Retina screen and I noticed that whenever Rocket.Chat+ is running on the Retina display, the fans are spinning like crazy and the Rocket.Chat client by itself gets really unresponsive and laggy.

Whenever I move the application from the MacBook screen to my (non-retina) Cinema Display, the application is fast and the lag/performance issues are gone immediately.

I made two comparison GIFs to show you the issue:

Retina display (laggy) - alternative .mov

Cinema display (no lag) - alternative .mov

Any ideas?

Crud, I just noticed that i should have probably raised this issue in the https://github.com/RocketChat/Rocket.Chat.Electron/ repository.

@frdmn Had you downloaded the app from the Map App Store?

If yes, can you try the DMG version? https://github.com/RocketChat/Rocket.Chat.Electron/releases/tag/1.3.0

I'd test here and this happens for me only when I'm using the version distributed via Mac App Store. If you confirm I will open a new issue on the electron's repository.

Thanks

I will move this issue to the correct place
