Windows 10.0.18363 x64 - GIT

SourceTree version 3.3.9

I have this very frequent bug lately (multiple times a day). When I view the files diffs (staging or commit), if I scroll down to the bottom of the file, it will freeze the UI and I have to close the process to restart.

Not all files trigger this freeze, but when one does, it will freeze everytime when I scrolldown (so I can reproduce the bug easily on my end). It seems related to the Diff "context" since, when I reduce it, the freeze doesn't occur on the same files (behavior change).

The freeze is instant, as soon as the Diff panel hits the end-of-file, it freezes.

I didn't have this bug in the previous version (3.3.6)
