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?)
Yes. A bitmap font I think? It's the xfonts-terminus Ubuntu package. http://sourceforge.net/projects/terminus-font/
No problem here - do you have the "bold" variant of the font installed (despite it looks exactly like the regular one)?
I think so. I have several *TerminusBold*.psf.gz files in the right directories.
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.
any update considering comment #8?
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.
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.
Seem to be gone. I haven't seen it anymore.
