screenshot LO 4.2.0 vs 4.3.4
tested under Win8.1 using LibO 4.3.4.1
some details of the rendering look even worse than 4.2.0 (see upper border of Help and Extension buttons and right border of the 3rd thumbnail)
moving this to mab4.3 list since 4.2.x is EOL

More information about daily builds can be found at: http://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback. I installed http://dev-builds.libreoffice.org/daily/master/win-x86@39/2015-01-29_15.54.41/master~2015-01-29_15.54.41_LibreOfficeDev_4.5.0.0.alpha0_Win_x86.msi and problem is solved. Can you please make the fix work for 4.4.0.3? billy78, If you need pretty scaling, use 4.5. But, this patch should not be backported until all the regressions are worked out like Bug 88841. It's causing a MAB4.5 drawing issue under Linux. 4.4 EOL - removing request. The original cause of the change in rendering from 4.1 to 4.2 : https://cgit.freedesktop.org/libreoffice/core/commit/?id=2e5167528f7566dd9b000e50fc1610b7bf99132a |
Created attachment 92878 [details] This document looks ugly in 4.2.0. Pictures inserted in documents that have to be scaled down look really ugly (using the most trivial scaling algorithm) when displayed on the screen. See the attached document in master, compare to 4.1 where it looks nicely. I'll attach also the screenshot of the ugly rendering.
