Attachments: Duplicate fonts window

Duplicate fonts window

SUMMARY
These "duplicates" are actually not duplicates

STEPS TO REPRODUCE
1. System Settings -> Appearance -> Font Management
2. Click the "Find duplicates" button
3. Check the result of duplicate fonts

OBSERVED RESULT
As in the result, many fonts are marked as duplicates but none of them are real duplicates. For example, NimbusSansL-Bold.ttf and NimbusSansL-BoldCond.ttf actually look different, the later is more condensed.

EXPECTED RESULT
These visually different fonts should not be marked as duplicates

ADDITIONAL INFORMATION
Comment 1 Nikos Platis 2024-05-08 15:04:55 UTC
I would expect "Duplicates" to refer to fonts that exist twice in the system, by mistake. Instead, I, too, am getting a list with some of my fonts, for which there is no info about the duplication. On the window, the last column is empty for all suggested fonts.
