I'm not focused on Sourcetree, yet process explorer tell me that sourcetree's child git processes are eating nearly 100% of the cpu on all cores (An i7 6700K is 4-core with hyperthreading, so 8 logical cores). I do have an image of this, but i cant figure out how to add to the ticket.   I have 6 repo tabs, and 2 submodule repo tabs open (both submodules are the same repo attached to different parent repos), one of the main repos is very binary-file-heavy with images and music, and most of the main repos have 30+ branches. It seems very similair to this issue from the Mac version as when i collapse the branch lists it seems to let up. https://jira.atlassian.com/browse/SRCTREE-1064
