examples of incorrect (phantom) spacing

See the attached spreadsheet which shows that characters c and w have additional empty space following, e.g. making "weg" appear as "w eg" when using 8 point formatting.
Similarly, c has empty space following for both 8 and 10 point sizes.

It seems this might be fixed with the new font layout engine of 5.3.
Could you please test 5.3: http://www.libreoffice.org/download/pre-releases/

Set to NEEDINFO.
Change back to UNCONFIRMED, if the problem persists. Change to RESOLVED FIXED, if the problem went away.

5.3.0.3 64 bit fixes the letter "w" but the letter "c" is still a problem, see screenshot...

I don't see the kerning problem. I have ClearType enabled in Windows.

This could be another duplicate of the bug 88991 (the root cause being the bug 103322).

Hello Aprax,
A new major release of LibreOffice is available since this bug was reported.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

in v 6.2.2.2 it's now working properly for all the fonts that I've checked so someone inadvertently fixed it without updating this ticket/report.
So I'd say it "Resolved" "Fixed" is the correct status.
