Created attachment 135112 [details] Test document Seen in 5.3.5.1 and 5.4.0, but almost surely introduced much earlier. Consider the test case in demo.odp. This contains a presentation with a single slide whose content is the logo of the University of Bologna in vector format (taken from wikipedia and converted into emf with inkscape). At some zoom factors, the image gets corrupted with parts of it being filled in, as the screenshot shows.
Created attachment 135113 [details] Illustration of the issue
The issue is problematic, because it is unclear whether it occurs only while editing drawings and presentations or it is possible even when /playing/ presentations. Furthermore, it happens either with: - EMF/WMF vector images - SVG vector images - native vector images Hence, all vector image formats seem to be affected, apart from PDF in LibO 5.4 that has other issues (lack of background transparency).
Disabling the anti-aliasing prevents the issue from occurring (but obviously the appearance is very much worsened).
I can't reproduce it with anti-aliasing on Version: 6.0.0.0.alpha0+ Build ID: 3f16306964d5bb81dda3c681bcabbacadf424e7b CPU threads: 4; OS: Linux 4.8; UI render: default; VCL: gtk3; Locale: ca-ES (ca_ES.UTF-8); Calc: group Could you please paste the info from Help - About LibreOffice? OTOH, to be certain the reported issue is not related to corruption in the user profile, could you please reset your Libreoffice profile ( https://wiki.documentfoundation.org/UserProfile ) and re-test? I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the issue is still present
Version: 5.4.0.3 Build ID: 92c2794a7c181ba4c1c5053618179937228ed1fb CPU threads: 8; OS: Linux 4.10; UI render: default; VCL: kde4; Locale: it-IT (en_US.utf8); Calc: single Wonder if the issue can be related to the specific graphics processor. Working on intel haswell mobile, and latest intel stack and mesa from git (oibaf ppa on kubuntu). Please make sure you repeatedly try all zoom factors pressing the + and - buttons many times until you have a huge or very small image: the fill-ins are totally erratic.
I tend to see the misrendering more often at zoom factors > 1000 or < 10. However, in other cases and with other images I have seen them even at much more common zoom factors.
Incidentally, the bug is also occasionally evident in the slide thumbnails in the slide sorter on the left.
I zoomed in and at 390% it already showed a block and with the next step, 440%, it was massively blocked out. No repro with GTK3, but does repro with all other backends. Arch Linux 64-bit, KDE Plasma 5 Version: 6.0.0.0.alpha0+ Build ID: 3c49b28ffa7ab062726e5e600312d9164224404e CPU threads: 8; OS: Linux 4.12; UI render: default; VCL: kde4; Locale: fi-FI (fi_FI.UTF-8); Calc: group Built on August 26th 2017
