Created attachment 166675 [details] Sample document (ODP format) Viewing slide 3 of the attached document in edit mode two or three images appear blurred. This is a regression between LibreOffice 6.4 and 7.0 / 7.1. How to reproduce: - open document - use <PageDown> tfwice to move to slide 3 - observe two or three of the images appearing blurred - observe how nothing appears blurred by invoking presentation mode with <Shift><F2> Broken in 7.0.3.0.0+ Build ID: 4ee6b9857d651d4bc7667227de4381286f3a9233 CPU threads: 8; OS: Linux 5.8; UI render: default; VCL: gtk3 Locale: en-US (en_US.UTF-8); UI: en-US TinderBox: Linux-rpm_deb-x86_64@86-TDF, Branch:libreoffice-7-0, Time: 2020-10-13_18:31:04 Works just fine in 6.4.8.0.0+ Build ID: 99b065ec31d032fc08ab14f66430dac4fef904a5 CPU threads: 8; OS: Linux 5.8; UI render: default; VCL: gtk3; TinderBox: Linux-rpm_deb-x86_64@86-TDF, Branch:libreoffice-6-4, Time: 2020-10-08_08:57:08
This is *not* Bug 129244 ("FILEOPEN: Blurred EMF image") since those images are not EMFs, but JPEGs. Axel, this is a bit similar to bug 137472 you reported.

As the original reporter I wanted to verify the fix - thank you, Lubos! - alas cannot reproduce the issue with all older versions I have installed (7.0 - 7.3 builds). This doesn't mean there was no issue (others confirmed) nor that the fix is not real - just that *I* am not able to confirm the fix. -> Attila or Axel?

Sorry no, I was unable to install the daily snapshot... But as we are on 7.2.5 in TW in between I can confirm that the fix works -> no more issues with the sample document!
I could verify the fix with a different sample I had at hand. The issue is gone in 7.4.0.0.alpha0+ (c13db6e792cc347ffff4585f23866f195651f21f) / Ubuntu, thanks Luboš! And indeed, with the original sample, attachment 166675 [details], the bug isn't reproducible for me anymore even in older builds, before the fix.
