ehm... it's stranger - it happens only when conditions:
Cmp files about ~5k lines.
3-way.
- no white line on the end (always 100%)
- then add line are on the end of 1st file on left
--- then I could remove it and CPU usage is low (1 core btw.)
--- viewport not on the end of file and cursor outside of viewport (but not repetitive on new instance, much less unresolved diffs was when it not happend...)
