I've also been experiencing this issue. My solution since November has been to add additional .desktop files to ~/.local/share/applications which start the app using QT_QPA_PLATFORM=xcb. This works for me, except of course, the X11 version looks odd with fractional display scaling (1.5x). Setting SAL_USE_VCLPLUGIN=gtk3 doesn't have issues with scaling, but scrolling is still inefficient and stuttery. It is much better than native, though, but causes the same spike in a single CPU core before stuttering when scrolling through long documents. The xcb version, however, barely uses any CPU no matter how fast or far I scroll in said long document. Since such smooth performance is available via XWayland while still running under a Wayland session, it makes me wonder whether the root problem is within Wayland itself or within LibreOffice's implementation thereof.
