Description Björn Lindqvist 2015-12-18 16:37:25 UTC
I'm using the terminus font in kwin and in some places the text just disappears. For example, it happens in some alt+tab window switcher modules. It only happens with the Terminus font so I can't say if it is the font that is the problem, the font rendering libraries or kwin. Screenshots attached.

Reproducible: Always

Is that a raster font? (Link?)
Comment 5 Björn Lindqvist 2015-12-18 17:22:24 UTC
Yes. A bitmap font I think? It's the xfonts-terminus Ubuntu package. http://sourceforge.net/projects/terminus-font/
Comment 6 Thomas Lübking 2015-12-20 21:42:10 UTC
No problem here - do you have the "bold" variant of the font installed (despite it looks exactly like the regular one)?
Comment 7 Björn Lindqvist 2015-12-21 07:39:15 UTC
I think so. I have several *TerminusBold*.psf.gz files in the right directories.
Comment 8 Thomas Lübking 2015-12-21 08:12:24 UTC
Does it show up in the "kcmshell5 fonts" config dialog?
It would be my first candidate, because the failing tabboxes use bold glyphs (where the breete one doesn't), butmap fonts cannot (really) be synthetically emboldened and since it also looks like the regular variant, it's rather pointless.

=> please check rendering of the bold font in the fonts kcm.
Comment 9 Martin Flöser 2016-09-14 13:59:13 UTC
any update considering comment #8?
Comment 10 Björn Lindqvist 2016-09-14 14:35:43 UTC
Ehm I'm not sure I understand Thomas comment. Terminus' bold variant shows up and is selectable in the font config dialog. I don't know if it is the synthesized bold or the real bold font that is used. I'll check if I have the same problem in Arch Linux which I think I do.
Comment 11 Björn Lindqvist 2016-11-18 13:01:22 UTC
FYI, I have upgraded to Ubuntu 16.04 and I haven't seen the problem yet. I'll let you know in two weeks if the problem is gone for good.
Comment 12 Björn Lindqvist 2016-11-26 13:41:10 UTC
Seem to be gone. I haven't seen it anymore.
