== The issue ==
\nSearch and text selection highlighting visuals get mismatched with the actual selection in view-source when the value of `layout.css.devPixelsPerPx` is 1.2 or larger.<\/p>\n
== Steps to reproduce ==
\n* Open `about:config`, find `layout.css.devPixelsPerPx` and change the value from default (-1.0) to 1.2.
\n* Open a view-source view with long lines: `view-source:https:\/\/www.youtube.com\/user\/10asti10`
\n* hit Ctrl+f, search for rss
\n* using the LMB, try selecting some text, then copy and paste it somewhere<\/p>\n
== What happens ==
\nScreenshot 1: the highlighted text on the page is not ”rss”. The highlight doesn’t even adhere to letter widths.<\/p>\n
Screenshot 2: the pasted text is not even close to what you’ve selected to copy.<\/p>\n
== What I expect to happen ==
\nFor the search to hightlight an occurence of ”rss”, and for the pasted text to correspond to what I’ve selected from the view-source view.<\/p>\n
== Other info ==
\n* In my testing, a devPixelsPerPx value of 1.1 seems to not trigger this, whereas 1.2 and anything above does.
\n* In addition to 18.04 (whence the attached info is from) I’ve reproduced this in a VM running up-to-date 18.10.<\/p>\n","protected":false},"excerpt":{"rendered":"
