Source Tree is showing changes when they are none

[dNazarik]

I work in Unity. All the time when I switch between branches I getting 1 unstaged file that locks everything. Source Tree says that file have been changed, but it is not. After reset this file becomes "changed" again. To switch branch I should commit this file. By the way this file is different in different branches. It could be LightingData.asset or some *.dll.

My .gitattributes:

Any ideas?

If you're working in Windows it could be the EOL problem.Most source/origin repos are stored in LF-only format while Windows insists on CRLF format. Git is supposed to be able to switch those back and forth on the fly as needed, but we have never gotten it to work properly all the time.

When you get these rogue files, switch the diff view settings from "Ignore whitespace" to "Show whitespace" (top right corner of Modified files panel). If you see a wall of pink when you show whitespace diffs, you have the EOL issue. I believe that's a Git problem, not Sourcetree.

"Show whitespaces" was enabled. Still "no changes" for .dll file.

Ok, if it is really GIT problem, how can I fix it for myself?
