Created attachment 2133 [details] screenshot normal size of systrayicon Linux arch35 5.9.6-arch1-1 #1 SMP PREEMPT Thu, 05 Nov 2020 21:00:46 +0000 x86_64 GNU/Linux lxqt-panel 0.16.1-1 claws-mail 3.17.8-1 Since update lxqt 0.15 -> 0.16 the claws-mail SysTrayicon in panel appears too big and has no functionality anymore on right/left click on it. If you left click on panel, choose 'configure panel' and close the dialog window the claws-mail icon reverts to normal smaller size and functionality is back (focus claws-mail on left-click, options-menu on right click). I remember this issue from LXDE some years ago.

Unfortunately no one seems to take care about this bug since I've reportet it half a year ago. Meanwhile the LXQt project abadoned the 'legacy/obsolete tray' and makes use of statusnotifier (libappindicator-gtk3 / libappindicator-gtk2) now. Claws-Mail icon does not work with this solution either! Now no icon appears at all when using the notification plugin. The developer of LXQt (tsujan) pointed me again to claws-mail in order to 'to remind its devs that it's 2021' (what ever that means).
