i'm running kde plasma on my mobile phone in chroot debian12 with zink on turnip. zink cannot create from pixmap properly when working with turnip vulkan driver, and even with amd radv the content is blurry. please implement software based texture from pixmap window content processing. that may also fix the same problem when running kwin with nvidia prime offload
