Take the presentation from attachment 184643 [details] of bug 153011. In presentation mode (only) the two boxes in the upper row feature two *very* different shadows than in edit mode or earlier versions. This is a regression between Version: 25.8.0.1.0+ (X86_64) / LibreOffice Community Build ID: 5136f42ad575a11f5955bd8289bbc10425944b33 CPU threads: 12; OS: Linux 6.15; UI render: default; VCL: gtk3 and Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: ccb3362a71f88213615bd39bd819ab8ec20d86cc CPU threads: 12; OS: Linux 6.15; UI render: default; VCL: gtk3 To make things worse, 26.2.0.0.alpha0+ seemingly randomly shows different shadows/effects. Always incorrect, sometimes different from run to run.
Created attachment 202260 [details] Visual comparision before (top) - now (bottom)
(Note how the effect for the left box is much, much larger/wider/taller).
bibisected with linux-64-26.2 (openSUSE+GNOME) In my case, it happens about 1 in 25 times. commit 09298d001e98ed494ecb1df5cb563b081da050e8 author Noel Grandin <noelgrandin@gmail.com> Tue Jul 29 19:59:53 2025 +0200 committer Noel Grandin <noelgrandin@gmail.com> Thu Aug 07 13:09:57 2025 +0200 tree fa9dad6611db6d22c08d45e6460fe9ef994a3b9f parent 3a02dd3d1cee8abed7fa1de9c1e6c2368dab5fcc [diff] BitmapEx->Bitmap in bitmapExFromXBitmap now that Bitmap can handle transparency Change-Id: Id87889a0e5ca0a3398f9baceee3474369eb0f7aa Reviewed-on: https://gerrit.libreoffice.org/c/core/+/188539
