Description V Stuart Foote 2024-04-11 21:41:45 UTC 
Was looking at attachment 187722 [details] from bug 150531

It is an ODF Drawing .odg with an SVG stream and an inserted PNG of the same image at 4600ppi

The images on the ODF drawing are a math formula, with the PNG created with the TexMaths extension.

When opened with Skia Vulkan rendering the PNG does not show, it is fit to page margins. With Skia raster framing or only GDI rendering the PNG is shown.

Affecting Win10 and Win11 systems with nVidia and Intel GPUs respective, both with current Vulkan drivers.

Could have been present with OpenGL rendering, a 6.4.7.2 build crashes with OpenGL rendering of the PNG--it also is fine with GDI
Comment 1 V Stuart Foote 2024-04-11 21:51:55 UTC 
This one is kind of odd, given the high ppi PNG renders to LO canvas with other filters, OpenGL era crash/recovering and Skia Vulkan rendering blank to canvas (but at the correct object frame) seems buffer.

Nothing jumps out with windbg attached.
Comment 2 V Stuart Foote 2024-04-11 21:55:09 UTC 
... seems buffer size issue?
