UI freezes when opening large repository

[Deaod]

Version info

• OS: Microsoft Windows [Version 10.0.19045.4651]
• Build: 2096
• git: git version 2.45.0.vfs.0.0

Description

UI freezes after opening repository, updates to show all files as staged, then freezes again

Steps to reproduce

Steps to reproduce the behavior:

1. Clone repository like so:
   1. scalar clone -b "main" --no-src "<repository>" "D:\WS\main" -> Your branch is up to date with 'origin/main'.
   2. pushd "D:\WS\main"
   3. git lfs install -> Git LFS initialized.
   4. git sparse-checkout set --cone --no-sparse-index [...] ->

Receiving packfile 76/76 with 3044 objects (bytes received): 10323864, done.
Updating files: 100% (351729/351729), done.
Filtering content: 100% (30110/30110), 27.96 GiB | 117.97 MiB/s, done.

2. Open repository in SublimeMerge

Expected behavior

I expected the UI to not become effectively unusable.

Debug Information I grabbed the debug information immediately after opening SublimeMerge, before the Stages Files were evaluated.

Screenshots

Freezes on this for a while (i presume its loading data in the background):

After presumably loading data it reaches this state: Any Interaction after this will freeze the UI again without ever progressing.
