Dear all, there were some discussions on pdf viewers on the list and I know that things are not always fine. I now have a problems with the Firefox pdf viewer and TeX Gyre Heros. The font looks uneven in FF, no problems elsewhere. When I scroll into the pdf to set the display to 150% or more the font shows up just fine. So it seems to be a display problems with firefox. I tried several pdf versions no change. My configuration: \definefontfamily[mainfont][serif][texgyreheros] \definefontfamily[mainfont][sans] [textgyreheros] \definefontfamily[mainfont][mono] [texgyrecursor][features=none] \definefontfamily[mainfont][math] [texgyrepagellamath] \definefallbackfamily [mainfont] [rm] [Latin Modern Math] [scale=0.925, range=0x22C0] \definefontfeature[smallcaps][script=latn, protrusion=quality, expansion=quality, smcp=yes, onum=yes, pnum=yes] \setupalign[hz,hanging] \setupitaliccorrection[global, always] Is there anything I can do? And the is another issue: To my big surprise ArialBold MT is included into the file. I am using the current lmtx. If you want to see the effect, download the pdf. https://www.hostsharing.net/publikationen/vereinshandbuch/ Just click on "Anonym herunterladen" no need to register.
