Exactly as stated in the summary. Moving slides when using the gtk3 VCL works as expected. Version: 24.8.3.2 (X86_64) / LibreOffice Community Build ID: 480(Build:2) CPU threads: 20; OS: Linux 6.11; UI render: default; VCL: qt6 (gtk3) Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded
Yeah, kf5 seems fine and thus we can't bibisect this as the repositories have not been built with kf6/qt6. Could be an implementation error.
Works for me with QT_QPA_PLATFORM=xcb, i.e. on X11/XWayland (even though the drag cursor shows a "stop" sign), but not on native Wayland.
