[Ubuntu] Distorted content while scrolling inside a Pdf file in Print Preview (Landscape mode only)
[Affected versions]: - 60.0.1 (20180516032328) - 61.0b10 (20180530184300) - 62.0a1 (2018-05-30) [Affected platforms]: - Ubuntu 16.04 x64 - Ubuntu 14.04 x32 [Steps to reproduce]: 1. Launch Firefox 2. Open a .pdf file inside the browser 3. Go to Print Preview (File - Print Preview or Menu - Print) 4. Change the orientation mode to Landscape 5. Scroll down the page and observe the behavior [Expected result]: - The scrolling is smooth, there are no rendering issues. [Actual result]: - The content slides along with the scroll and part of it disappears in this process(https://drive.google.com/open?id=1yaxSHl_8iX-OSkqibSP6ShqV8PcGqx_0) [Regression range]: - I manage to reduce the regression range to the followings: Last good revision: c750a7de1194d71f2d2ef73f6a919d26b9640cae (2016-12-15) First bad revision: 63b447888a6469b9f6ae8f76ac5f0d7c6ea239da (2016-12-16) Pushlog: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=c750a7de1194d71f2d2ef73f6a919d26b9640cae&tochange=63b447888a6469b9f6ae8f76ac5f0d7c6ea239da [Additional Notes]: - This issue is not reproducible in Portrait mode. - This exactly behavior is not triggered on OS X and Windows platforms, but when in Landscape mode the bottom of the page is cut off (see bug 1430114). - This behaviour can be observed, only when the scale is set to 100% or to “Shrink to Fit”.
Here is the pdf sample that I use to reproduce this bug: http://www.dbsparks.com/research/html/SNRN02.pdf, plus a correction for the flag settings.
