Description Alexey 2015-04-15 07:15:10 UTC

I'd like to use my favourite Anonymous Pro bold font for Konsole, in kde4 everything was good. But in kde5 I see that this font renders incorrectly in Konsole. 

Reproducible: Always

Steps to Reproduce:
1. Set Anonymous Pro font, font size matters, it must render in native size, eq 10 on 96dpi.


Actual Results:  
Konsole cuts font height.

Expected Results:  
Fine font rendering

I can confirm this bug with Anonymous Pro font. It appeared approximately at the end of march or beginning of april (in Arch repository). Only the upper half of the characters are visible.
Font size matters, because these font sizes are good: 7, 11, 12, 13, ...
Font sizes which behave badly: 8, 9, 10.

This is what we can see with Anonymous Pro font (size 10).

this looks very similar to bug #342188

Comment 4 le.trmr 2015-09-25 09:56:15 UTC

The same behaviour is present in Kate.
As the fonts author points out, this could be connected to wrong handling of embedded bitmaps. (http://www.marksimonson.com/info/anonymous-pro-usage-notes)

Hi, for me, with Qt 5.5 + KDE Frameworks 15.14 it works.
Even if you can reproduce this, please report it upstream to Qt, we can't fix the font handling there, we rely on Qt to do it right.
Tried on current arch here.

No problem with QtCreator.

Comment 8 Jean-Michaël Celerier 2015-11-17 19:57:02 UTC

I added two attachments that show the problem occuring with KDevelop but not with QtCreator (they were both built against the same Qt libraries on my computer).
