with sealert running under kde4, one sees it's systray icon misrendered (wrong size mostly). Per http://bugs.kde.org/155381 I traced this down to sealert drawing the wrong size (32x32 minimum). $ xwininfo -tree ... [click on Plasma now] 0xc3000020 "sealert": ("sealert" "Sealert") 32x32+0+0 +1238+764 ... $ xprop -id 0xc3000020 ... WM_NORMAL_HINTS program specified minimum size: 32 by 32 ... Needless to say, the standard kde systray size is smaller than 32x32.
alrighty, looks like upstream kde is going to workaround this and other ambiguities in the systray spec. sorry for the noise. *** This bug has been marked as a duplicate of 440031 ***
