Broken screen resolution data

I’ve noticed a lot of broken screen resolutions in my Piwik 2.14.2 visitor log today:

Firefox
Mac 10.8
Resolution1440.0000

Chrome
Windows 7
Resolution1848.0000

Firefox
Windows XP
Resolution1279.5652

Internet
Windows 8.1
Resolution1366.0499

Internet
Windows 7
Resolution1920.0000

Internet
Windows 7
Resolution1600.5x90

Is that related to Incorrect screen resolution detected for devices with device pixel ratio > 1 · Issue #7941 · matomo-org/piwik · GitHub ?

Hi there,

Can you paste some screenshots showing the problem?

I can but what additional value do you get from this?

Hi there,

I am experiencing the same issue, is there any news?

Thank you!

@matthieu, I was able to reproduce it. Look for 1679.5999 in this API call:

Thanks for the report. We will fix this soon. Here is the bug: Screen resolutions may appear with decimal such as 1279.5652 and may be truncated · Issue #9911 · matomo-org/piwik · GitHub

This should be already fixed in Piwik 2.16.0, please update.

Yes, it looks okay in 2.16. Thank you!
