1127485 - Fuzzy text rendering after scrolling

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: Toolbar, defect)

Description

Attachment: fuzzy.jpg

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.93 Safari/537.36

Steps to reproduce:

When I visit certain pages (this one, for example: http://www.itworld.com/article/2693419/hardware/how-to-build-a-rack-mounted-server-from-scratch.html) and scroll down when reading, the browser sometimes doesn't finish rendering the newly shown part of the page, the text stays fuzzy. Sometimes it then completes the rendering (after 5 seconds or more), and sometimes it stays that way until I scroll up and down a bit. 

I can reproduce this behavior on that page by reloading it, but it's difficult to reproduce it exactly due to the imprecision of swipe scrolling.

If you can reproduce this problem and are comfortable with getting a logcat dump from the phone please let me know. I can give you a special build with extra logging enabled that will help us track down the problem.

If the dump doesn't contain any sensitive personal info, I have no problem with doing that.

Thanks! There is a build at http://ftp.mozilla.org/pub/mozilla.org/firefox/try-builds/[e-mail]-70d5ebd9a779/try-android-api-11/ (the .apk file) which you can download and install to your phone. It will install as "Nightly" (I'm assuming you don't have Nightly already installed). Please use that, collecting the logcat as you do so. Once you reproduce the problem (i.e. the blurry text is visible on your screen and isn't going away) please stop the logcat collection. That way the most relevant logs will be right at the end of the log.

If possible please collect logcat using "adb logcat -v time" so that timestamps are included, as that will help isolate the problem.

The dump shouldn't have any sensitive personal info, although occasionally URLs end up in the dump from script errors and such. If you would prefer you can email me the log directly rather than posting it here on the bug.

Thanks!

Sorry for the late response. I've installed the Nightly, but I cannot reproduce the problem so far (neither on Nightly nor on the newly updated official version). However, I did notice some new strange things on the official version, I will send the logs to you if I'm able to reproduce them on Nightly.

Also, the new official version seems to be even more unstable than the previous one - it now crashes several times a day (even when I'm not actively using the browser and some other app is in the foreground).
