--- Comment #9 from Luboš Luňák <[email protected]> --- The Skia case is slow only with Vulkan. The comes from https://cgit.freedesktop.org/libreoffice/core/commit/?id=8ca549ebc01a7aa0b288c521a9e60e76f4d8e97d (the Cairo commit is https://cgit.freedesktop.org/libreoffice/core/commit/?id=cf9be3417bc2be5f772c03180b7cbd248b82cad5). What seems to happen is that impBufferDevice tries to copy a small part of a GPU-based image to a raster-based image because of that commit, and that causes fetching of GPU data in this case. So basically a pick-your-poison situation, as long as we have to deal with the split alpha hack. -- You are receiving this mail because: You are the assignee for the bug.
