False Negatives when switching between Resolutions

Open egucciar opened this issue 7 years ago • 2 comments

Seeing a significant amount of false negatives between resolutions - i.e. switching from big screen to small laptop screen. How to prevent?

Can you post an example here? Even tho I think I know what you mean ... the way I currently scale the screenshots so they can be compared no matter what the screen size of the test runner window was, causes edges to be falsely detected as differences 😕 Not sure atm how to prevent it without increasing the threshold, but I'll look into it :+1:

@julianburr I'm pretty sure this happens so consistently that you can easily reproduce with the following

  • With open, run the suite in full screen and run again when the screen is resized to be smaller
  • With open, run the suite in full screen on a large monitor and run again in a small monitor
  • With run (once you fix it on your end), on two different machines

I'm sure open will also fail on two different machines.

It's very consistent
