Describe the bug / provide steps to reproduce it

as we all know, ( #8436 #7939
zed have some tiny memory leak(?) issue since sometimes ago
some how, it will only increase the memory usage for about 1mb/min ( on my windows 10 )

but at some times the memory leak issue became FAST

Environment

Zed: v0.139.0 (Zed Dev 29b5253)
OS: Windows 10.0.19045
Memory: 95.9 GiB
Architecture: x86_64

but after the commit 94c3101, the memory leak issue became FAST

That commit didn't change anything on Windows or macOS. It only affects Linux code.

If you want to help track down the memory leak, use a tool like the Visual Studio memory profiler and post the memory dump here.

After a session of debugging and tracing, it seems like the issue is not in zed itself, but in blade_graphics implementation of the Vulkan backend. reset_descriptor_pool resets all the sub_pools, however, when we allocate a new descriptor via alloate_descriptor_set, it only uses the latest pool, it doesn't actually reuse the previous pools.

I confirm the issue is in blade_graphics, and specifically, Intel HD graphics driver, not zed. kvark/blade#117

hmmmm, so there's the problem, my gpu are AMD RX580, so it's possible not just an intel only issue, or it's anther issue

FYI

So the issue with Intel HD Graphics is solved in kvark/blade@845cdad, but the zed master branch is still on an older commit it seems.

I am having the same problem.

Zed.log seems to be looping over a git error infinitely for as long as the program is running:

2024-07-06T12:05:50-07:00 [ERROR] Error 
{ code: -9, klass: 4, message: "reference 'refs/heads/master' not found" } x500

This is a git error, however the constant error loop is causing a memory leak if I open a project with no git open, zed doesn't leak memory.

Environment

Zed: v0.144.0
OS: Windows 11 Home 10.0.22631 Build 22631
Memory: 32 Gib
Architecture: x64-based PC

1. Is this still an issue?
2. I recall this could occur when git init had been run in a project directory, but there were not yet any git commits. Does this match your situation?

[shenjackyuanjie]

is not an issue anymore, but I'm not sure if we'll meet it again
git looks like anther issue, and I'm not sure about it
