Describe the bug / provide steps to reproduce it
When I compiled the code from source by using this guide developing_zed__building_zed_linux.md and after the compilation when it's open only for hovering over application the CPU picked at 100%
Environment
OS: Pop!_OS 22.04 LTS x86_64 Host: VivoBook_ASUSLaptop X415JA_X415JA 1.0 Kernel: 6.8.0-76060800daily20240311-generic Packages: 3819 (dpkg), 45 (flatpak), 16 (snap) Shell: bash 5.1.16 Resolution: 1920x1080 WM: i3 CPU: Intel i5-1035G1 (8) @ 3.600GHz GPU: Intel Iris Plus Graphics G1 Memory: 15737MiB

This is what get when open application from terminal.
I'm having a similar issue on fedora 36 on my desktop, however it might be my GPU/Driver related. vulkaninfo reports an error for me.
it does work fine on my laptop on both fedora 39/40.
Did you compile in release mode? If that's not the problem and it's also not the LSP then idk

Yes, I have compiled it in release mode sorry for late replied.
Do you have the Vulkan drivers installed? Can you run vkcube and show the command line output?

Hmmm, You seem to have the Vulkan drivers installed and working. So I don't think it explains the high CPU usage...
I do not think guessing is a good strategy here.
Linux has perf and other profiling tools, taking a sample of the 100% load is the next reasonable step to have this issue solved.
I have a similar issue, it turns out that LLVMPIPE was chosen as the graphics render, switching to a discrete graphics card solved the issue for me:

To switch the graphic card you can do the following:
- list availabe gpu :
MESA_VK_DEVICE_SELECT=list vulkaninfo, note the ids (the second column like 8086:166) - force zed to use the correct one :
MESA_VK_DEVICE_SELECT={id}! zed{id}need to be replaced with the correct id

Thanks, that also works.
Mine was driver related, Fedora & Ubuntu by default uses Radeon for my older card i have switched over to AMDGPU. It has resolved my issues. The 3D cube demo does work for both drivers.

Device should support my CPU is not that old right.

I found this according to the log the zed detect the NVIDIA so it rejects to use intel and end up using the llvmpipe
Possibly related, when opening Zed I see a blank window (no new content, it has a "snapshot" of other window's contents underneath the newly created window) and high cpu usage when moving the cursor inside it. I am on Qubes OS 4.1.2 with a Fedora 37 VM, only GPU available is llvmpipe due to the graphics stack of Qubes, so switching the GPU driver in use is not an option. Same result when using the install script, the release and nightly tarballs, and running from source.
From prior experience developing software on Linux, I usually see this "snapshot" behavior when a window is created but nothing is ever drawn to it. This is however not a recurring issue with other programs on my system.
Only quirk I noticed for a program I develop is that GLFW cannot detect the display FPS on my system (as per the isolation of the VM) and so swap interval does not aim for a fixed refresh rate but rather refreshes as quickly as possible. I mention this in case Zed is relying on a detected FPS value, and when this fails it simply draws nothing to the window. However I am led to believe that Zed is actually drawing fine and simply not committing to the window, since my CPU usage spikes when moving the cursor inside the blank window, and also considering the Refreshing at 16673 micros line in logs below.
