Font size too small in Opera browser

[MicroBeast]

Effect the main setting window. Especially the input box.
While in Firefox & other Chromium based browsers font size look like 12pt. Only in Opera the font looks like 8pt - 9pt. Worst yet, the font is Serif font. Which make comma (,) and poin (.) almost identical and unreadable. That's if we manage to read the rest. (Bad old eye here).
I suspected not really your extension fault. Opera fonts (dpi?) does seem more tight and smaller then even other Chromium based browsers.
So, this is not really a bug report. I just want to let you know.

Infos that seem matter:
Debian sid amd64
Opera 41.0.2353.69
Proxy Switcher & Manager 0.1.4
Monitor size 1440x900_60

Thanks.

Can you take an screenshot of the issue?

Ugh, sorry for late reply. This message buried under my gmail forum subfolders.

Forget about the issue (which not a problem). After further study, it seem it's Opera own issue. Font DPI seem all time lower than in this app compared to other apps.

We could close this.
Thanks
