Hyper: High CPU usage on macOS

[herrbischoff]

• [x] I am on the latest Hyper.app version
• [x] I have searched the issues of this repo and believe that this is not a duplicate

• OS version and name: macOS 10.13.4
• Hyper.app version: 2.0.0 (stable)
• Link of a Gist with the contents of your .hyper.js: shipped default
• Relevant information from devtools _(CMD+ALT+I on macOS, CTRL+SHIFT+I elsewhere)_: n/a
• The issue is reproducible in vanilla Hyper.app: Is Vanilla

Issue

Having lots of output scroll by fast (in this case, running portsnap fetch update via SSH on a FreeBSD box) causes very high CPU usage (~180%, up to 250% on a 2014 MBP), while identical output in iTerm (~30%) or Alacritty (~8%) does not.

Same problem with me... OS version (macOS 10.11.6).
Not possible to use Hyper anymore...

Do you have multiple graphic cards? Eg. nvidia dedicated card?

Ok, could you please try the latest canary release? It has disabled Chromium GPU blacklist (for webgl, so doesn't affect us), which has been reported to resolve this on windows 👍

canary release works for me. thanks

I have also tried the Canary version and it's working far better than Stable. It's still consuming rather large amounts of processing power but in my limited testing it has shown to cut this rate by about half compared to Stable.

However, the reason for this must lie elsewhere because the Chromium GPU blacklist (https://chromium.googlesource.com/chromium/src/gpu/+/master/config/software_rendering_list.json) does not contain my GPU (0x0d26 / 0x0fe9). The closest I have found is this entry but then again I'm using macOS 10.13.4.

hyper is still sucking up a lottttt of cpu...(using canary)

Closing, since this will obviously not be addressed.
