Can confirm this issue on Operating System: openSUSE Tumbleweed 20210704 KDE Plasma Version: 5.22.2 KDE Frameworks Version: 5.83.0 Qt Version: 5.15.2 Kernel Version: 5.12.13-1-default (64-bit)
Moving to kio-extras. Technically I think the PDF thumbnailer is in kdegraphics but that has no product, so to kio-extras we go! :|
Occurs for me on KDE 5.24 on Kubuntu 22.04. As with the original report, even from the same vendor, the behavior varies, and reading the PDF never shows a leading blank page.
FYI, I still see this in Kubuntu 22.10, Plasma 5.25.5 with kio-extras 22.08.2.
I have the same issue. Arch Linux, Kernel v6.4.12-arch1-1 KDE Plasma v5.27.7, Wayland
