Too many files will cause SourceTree to hang

Steps to reproduce

1. Create a folder 'FolderA' with 3500 new files
2. Switch to "File Status" tab
3. Set the view to be "Tree View"
4. Expand 'FolderA' to view all the files -> SourceTree hang
5. Restart SourceTree
6. Switch to "Flat List" single/multi column - no problem
7. Commit all 3500 files in the repo
8. Switch to "Log/History" tab
   It will select the first commit automatically. Trying to load 3500 files at the bottom will cause SourceTree hang too

workaround:

The issue is with performance in the treeview, to avoid this flat view's should be used in preference to the treeview.
There are currently two possible work arounds.

Workaround 1: Reset the User preference, in v1.6.9 to 1.6.11, to use a flat view

1. Shutdown SourceTree
2. Find the <Version>/user.config file in a folder below %localappdata%/Atlassian/SourceTree where <version> is 1.6.9, 1.6.10 or 1.6.11
3. Edit the user.config and set FileStatusViewMode to 0, i.e:

               <setting name="FileStatusViewMode" serializeAs="String">
                   <value>0</value>
               </setting>
   

4. Restart SourceTree

Workaround 2: Revert to 1.6.8
A workaround is by uninstalling the current version and install SourceTree version 1.6.8:
