Most likely a git issue:
I have filtered with Diff contains (SLOW). But the git command has not returned for almost 6 hours - I guess due to a child process astextplain. pdf2text.exe seems to block in conjunction with a pipe to "C:\Program Files\Git\usr\bin\sed.exe" s/(\^M$)|(^\^L)//.
After killing pdf2text.exe, another one is started for the next PDF.
These PDFs are stored in Git LFS. But the temp files have not been expanded.

This even blocks GE from switching repos.
I agree with @gerhardol: A yet running git log command should be canceled/killed when refreshing the RevisionGrid.
