High CPU usage on windows

[oleynikandrey]

Just started Hyper Terminal uses about 13% of CPU on Windows 10.

Hyper 1.0.0
Electron 1.4.7
win32 x64 10.0.14393

And that is only the main process. I have 4 additional processes running

What shell are you using with Hyper? (Options: cmd - default, powershell, native bash, maybe others I don't know). Are you using plugins? Try to disable them if you do and report back.

[oleynikandrey]

I have made no changes to default settings of Hyper. So it use cmd as shell and no plugins at all.

+1; also experiencing this issue.
default install and not even running anything ...

[omnicons]

Also experiencing this, though it is more pronounced when I get into zsh going up to about 7% usage

I also experienced, and also just the default experience. Made it unusable, had to close it and stop using. I will wait for a later release.

Just updated to 1.3.0 and CPU utilization is still quite high. About 30% constantly across the 4 processes. Also Windows 10 build 14393. I'm using Powershell.exe. My Config.

FWIW, after letting the window site idle for a couple of hours, I found CPU utilization to be near 0. I don't know really how long. That and JS profiling shows nothing leads me to believe it's some background task that eventually finishes or times out.

[cdhunt]

And I let it sit overnight and it's still using 30%+ CPU this morning. /shrug

This also happens to me on Win 10 build 1607, but only when I install hyper-tabs-enhanced. As soon as I remove it, CPU usage goes back to normal. Curiously, the Desktop Window Manager also cranks up at the same time.

Hyper 1.3.1
Win 10 1607

@cdhunt Can you try with a vanilla HyperApp. Without any (hyper-tabs-enhanced) plugin?

[cdhunt]

I was just testing and I can corroborate disabling hyper-tabs-enhanced reduces CPU usage to ~0%.

[chabou]

Great!
So we can close this issue (other feedbacks are old).

But feel free to reopen if last version of Hyper has a high CPU usage without any plugin.

Transferred issue to hyper-tabs-enhanced repository as henrikruscon/hyper-tabs-enhanced#13.

[pcnate]

I had a similar issue. I would verify if you have hyper-material-theme installed

[idanshimon]

this still happend on hyper 2.0.0. stable with hyper-tabs-enhanced plugin installed my CPU goes upto 100%
once i removed the hyper-tabs-enhanced plugin it resolved and cpu went down to 30%~

Can confirm this still happens on hyper 3.0.2 on Windows build 18362.388
Turns my laptop into a leaf blower with just cmd open. Installed today and made no changes to the settings or configuration.

Also confirming - build 1909. Used like 70% of my cpu.
