Hey, that was fast! Good work! Yes, I can confirm I have the co-installed libs in a working LXQt 2.0.0 setup on Tumbleweed with the X11:LXQt repo. I can confirm that theming and the LXQt file dialog are working equally in qt5 and qt6 apps now. As far as I'm concerned, this is solved as soon as it hits a snapshot. Related suggestion: I think that these two libs should probably be added to the lxqt pattern. Otherwise, they won't be installed by default, and many users won't know why qt5 apps don't follow user theming. Yes, libqt5xdg was automatically pulled in. Thanks!
