SUMMARY The coloured markers in the right-hand column do not align with the diffs in the text on my 3840x2160 screen. I've only ever used 1920x1200 before. STEPS TO REPRODUCE 1. Run kdiff3 on 2 files of non-trivial length on a large-screen monitor. 2. Note that the coloured markers in the rightmost column do not line up with the highlighted diff text. 3. Adjusting the screen height to make one marker line up compromises other markers. I'm using the default 10-pt fonts and settings migrated from my old 1920x1200 setup. OBSERVED RESULT Markers don't line up with marked text. EXPECTED RESULT Markers line up with marked text.
