I am getting unreadable tiny fonts in the notification box today. Never has any issues with that. The notification skin was updated yesterday.
3840x2160 rez with windows scaling set to 169%
Seems like any notification skin ignores the windows scaling now. I tried to change font size by editing a skin. Size did not change.
Haven't tested my other PC's yet with 1920x1080 yet.
I still have a copy of PP without the notification update.
Font size is good pre update.
After updating the notification skin, all font are tiny in all skins.
Ok, I have an idea of why the DPI setting probably isn't working. I used to use 125% and probably would have noticed the difference myself, but I went to 100% last year.
As for editing the skin manually -- I tested it myself and it works as expected. I suspect you weren't changing the right (or all) the controls (or maybe not saving the file?). And it's not necessary to restart PP after changing; if you're in the skin notifier settings, just press "test" after saving and it shows the updated skin.
There will be a fix coming. I'll need someone to confirm the fix before I release it, so please email me and I will provide further instructions -- this isn't ready yet so I may not reply until it's ready (which may be days, hoping sooner, but there's still a lot going on).
Also, if you modified an existing skin, you may want to make a backup of its ini file since the installation may overwrite the files; just in case something happens.
