Start Impress, insert an image and select it. Open the 'Image' toolbar in case it does not automatically opens. The 'Image' toolbar has a drop-down list for "Image Mode" (.uno:GrafMode) with items: Default, Grayscale, Black/White, Watermark. Select "Grayscale". Actual: Nothing happens Expected: The image is displayed in gray. I see the error in Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: b1c0c4838d2e006ffa8e72516569ce8d13bdbe01 CPU threads: 32; OS: Windows 11 X86_64 (build 26100); UI render: Skia/Vulkan; VCL: win Locale: de-DE (de_DE); UI: en-US Calc: threaded It was OK in Version: 24.8.0.3 (X86_64) / LibreOffice Community Build ID: 0bdf1299c94fe897b119f97f3c613e9dca6be583 CPU threads: 32; OS: Windows 11 X86_64 (10.0 build 26100); UI render: Skia/Vulkan; VCL: win Locale: de-DE (de_DE); UI: en-US Calc: threaded

Repro. For me the Image toolbar is overflowed and I have to access it by clicking the chevron and after closing and reopening it, the dropdown entry has returned back to Default.
