Zed.log
natemcintosh commented 1 month ago

I'm seeing something very similar. I checked out the advice on the linux docs page, ran vkcube, did not see anything about llvmpipe, but did see 

MESA-INTEL: warning: cannot initialize blitter engine
Selected GPU 0: Intel(R) Arc(tm) A750 Graphics (DG2), type: 2

I should note that when I run zed I do not see any GPU usage, but do see ~60-70% CPU usage (total of all processors, not on single processor).

I installed via

curl https://zed.dev/install.sh | sh

on 2024-07-10.

Also, where can I find the logs on linux? I ran

cd /
fd zed.log
fd Zed.log

But got nothing from either search.

Don't know if it's helpful, but in case it is:

Describe the bug / provide steps to reproduce it

I have a similar problem when using Zed. CPU usage reaches 80 to 90% every time I open a file from the project’s tree files and the editor is pretty slow I just installed Zed, so my settings are nearly default:

{
  "theme": {
    "mode": "dark",
    "light": "Ayu Light",
    "dark": "One Dark"
  },

  "base_keymap": "Atom",
  "ui_font_size": 16,
  "buffer_font_size": 14
}
