Thank you for filling out a Git bug report! Please answer the following questions to help us understand your issue. What did you do before the bug happened? (Steps to reproduce your issue) * open Git Gui in a repository from git bash ($ git gui&) * select some text in the diff pane What did you expect to happen? (Expected behavior) * selected text should be highlighted with white text on blue background (maybe it used to use system defined colors?) What happened instead? (Actual behavior) * selected text is highlighted with white text on black background What's different between what you expected and what actually happened? * The contrast has increased to a level that is painful for me to look at, making it difficult to read the selected text. * It also makes the experience of this tool different from gitk, making me focus on the tool rather than the content and workflow.
