Created attachment 161232 [details] embedded PNG is kind of low resolution to start Confirmed on Windows Version: 7.0.0.0.alpha1+ (x64) Build ID: b587de60d4e6aa96238766272d94f1499b22f696 CPU threads: 4; OS: Windows 10.0 Build 18363; UI render: Skia/Vulkan; VCL: win; Locale: en-US (en_US); UI: en-US Calc: threaded RenderMethod: vulkan Vendor: 0x8086 Device: 0x5916 API: 1.2.135 Driver: 0.401.4091 DeviceType: integrated DeviceName: Intel(R) HD Graphics 620 Blacklisted: no The rendering of the slide is visibly different between default GDI (with or without HA) and Skia rendering. Feels fuzzy with GDI, and pixelated with Skia (Vulkan or raster) so PNG image is getting different handling. But, maybe that is not the best image to have scaled for a presentation.
