Description: PNG with alpha, flip and set transparency, shows normal during editing, but shows the original image shadow during present. If only flip without set transparency, the result is OK. Both flip and set transparency will cause the problem. If the png image flips twice, the result is OK. Steps to Reproduce: 1. insert a png image with alpha channel 2. copy it and paste a new instance 3. set the new instance to transparency, like 50%, and flip it H or V. 4. present F5 to present this slide (or open the sample odp file and press F5) Actual Results: The flip + set transparency image shows the extra shadow, its shape is the original image. Expected Results: The flip + set transparency image should show normal during present, just like during editing. Reproducible: Always User Profile Reset: Yes Additional Info: Version: 7.5.4.2 (x86) / LibreOffice Community Build ID: 36ccfdc35048b057fd9854c757a8b67ec53977b6 CPU threads: 8; OS: Windows 10.0 Build 22621; UI render: Skia/Raster; VCL: win Locale: zh-TW (zh_TW); UI: zh-TW Calc: CL threaded

I see the problem in Version: 7.5.2.2 (X86_64) / LibreOffice Community Build ID: 53bb9681a964705cf672590721dbc85eb4d0c3a2 CPU threads: 8; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win Locale: de-DE (en_US); UI: en-US Calc: CL threaded If I disable Skia the shadow is not visible in show mode. I don't see the problem in Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: b3053b63c65372627c5fb4df6b4ddcd5e12e16f7 CPU threads: 8; OS: Windows 10.0 Build 19045; UI render: Skia/Raster; VCL: win Locale: de-DE (en_US); UI: en-US Calc: CL threaded The version 7.6 will be released this month. There is a prerelease available. I don't see the problem in that prerelease version. Perhaps you try it? On https://www.libreoffice.org/download/download-libreoffice/ scroll down to get it.
Then try to update the driver card from the vendor (AMD, NVIDIA, INTEL, ETC)
