Description:

I really feel uncomfortable with how LXQT ended up after qt5 upgrade, that I had to move to plain Fluxbox. I don't have a screenshot to provide, but at least the panel was really broken, with tray icons spreading all across the pane, and hiding the menu.

As LXQT build against QT5, my guess is that it should have been rebuilt against the QT5 upgrade

Misplaced... this should go in the community bugs. Sorry !

Filed it already on the right place I believe:

Attached you can find the effect when launching Xorg with lxqt as desktop... Yestarday and Today (weekend for me) I finally had some time to play a little bit more with this...

I found the issue doesn't seem to be the panel itself, but rather the icons. As you can see, even out of the panel, like the lxqt-leave drop down menu looks broken. The panel icons that look really bad when launching lxqt are the quick launch widget icons, the showd desktop widget, the volume widget, and teh removable media widget. As I had initially the show desktop widget besides the menu applications widget, the menu one was not accessible...

Experimenting further, I noticed at least the widget icons (I couldn't play with the quick launch ones though), show up just fine, if they're added to the panel once lxqt, the window manager, and everything is up and running already. Unfortunately the leave menu doesn't look any better, since it's always launched after everything is up and running any ways. However, it might be that menu is tight to something happening at the early lxqt stages, or there's still something wierd about icons support.

All that said, it seems like a raising condition at the early stages of lxqt affecting icons support, and in the case of menus with icons, something that remains even after everything is settled.

Just in case, using dark breeze theme and dark breeze icons, plus qt5ct using those as well.
Comment by Javier (je-vv) - Friday, 18 January 2019, 05:13 GMT
Changed icon them from dark breeze to dark papirus, and the same results...

The QT 5.12 update didn't just break tray icons for lxqt, it broke it for every window manager as far as I can tell.
See: https://github.com/i3/i3/issues/3589 for more details.

On i3-wm a simple i3-msg reload, i3-msg restart or a simple display output change will make your tray icons disappear while the parrent application keeps on running.

On my machine with QT_QPA_PLATFORMTHEME=qt5ct and breeze-dark icon theme, icons are gone (invisible) in lxqt-leave. On the other hand, QT_QPA_PLATFORMTHEME=lxqt + lxqt-qtplugin 0.14 + breeze-dark works fine if "Colorize icons based on widget style (palette)" is enabled from lxqt-config-appearance. I would say it's a qt5ct issue.

Alexander Kempen: that's a different issue. Icons gone != icons appear corrupted.
Comment by Javier (je-vv) - Wednesday, 30 January 2019, 18:22 GMT
I can confirm what @yan12125 indicated. By using the official 0.13.0 lxqt-qtplugin, and setting QT_QPA_PLATFORMTHEME=lxqt with breeze as the theme for LXQT (configured as dark on KDE settings), with official papirus dark icon theme, icons and the leave menu are working fine. I re-enabled the quick launch widget, and everything works. So yes, it might be rather a qt5ct defect. I'm not sure if lxqt-qtplugin also provides the dark breeze theme to all QT applications, but if so, that might be it for me, though on its github markdown (https://github.com/lxqt/lxqt-qtplugin) it says "With this plugin, all Qt-based programs can adopt settings of LXQt, such as the icon theme", not being explicit about other themes but the icons one...

BTW, at least for Arch, this can be marked as not a defect. By chatting on the #lxqt IRC channel, I learned for lxqt at least QT_QPA_PLATFORMTHEME must not be set at all, and lxqt-qtplugin must be installed, and themes, styles and so on should properly get propagated to all QT applications. I tried that (not setting at all QT_QPA_PLATFORMTHEME), and things kept working as indicated on #lxqt.

So in the end, at least for lxqt, this is not a defect. Whether this gets closed for lxqt, or gets renamed and repurposed for qt5ct, which seems broken, and needed for non KDE/LXQT environments.
