diff window is showing complete files
I was playing around with one of my repositories in order to be able to make diffs of some custom file type (.form files exported from MS Access files), added .gitattributes for that, also discovered the settings diff.context and diff.interHunkContext. Meanwhile I have set both values to 3, which I think should be the default anyway.
Now it seems, that Sourcetree does apply 100 for both those values, therefore displaying almost the complete file in the diff window, even if there is only one line changed. I can't see how or where to change this.
I even re-installed git (2.35.1.2) and Sourcetree (3.4.8).
As an example, this is the console output for "git diff":
And this is what Sourcetree is displaying:
This applies for all repositories and all file types.
How can I fix this?
