Version: (using KDE 4.3.1) Installed from: Unspecified This is a lousy cut and paste from bug 192919, I am opening new bug as requested. The problem persists with the latest and greatest constellation of everything (tm). Actually, it happens on multiple of configurations (including nvidia/ati video combos) and the common denominator seems to be Qt 4.5 (possibly 4.5.x) in combination with the KDE systray applet. I recently upgraded KDE to 4.3 (including Qt 4.5.2), and poof, icons vanished. Except for Psi, which is a Qt application, but was linked to Qt 4.4.x. When I recompiled Psi with Qt 4.5, its icon vanished. However, before we start pointing our fingers at Qt and generally away from KDE, I have discovered that on all the mentioned platforms, the problem happens ONLY when systray is a standalone applet and not a part of a panel (that might explain why some folks have a WORKSFORME). That's right: put the systray into the panel and we have icons, remove, put it on the desktop and we don't. (Just for the record, there is only one systray at any given time.) To summarise, the problem is that Qt 4.5 apps icons dont show in the systray, but only when the systray is floating on the desktop (versus embedded in panel). Icons that show are Kmix, the uninvited (i)nformation thingy (how do i get rid of it btw?) and generally anything that is not Qt 4.5 (Qt apps linked to <= 4.4, GTK apps, and so on). To be precise, the icons DO show, but mostly as a fully transparent box, or, if you're lucky enough, random junk, but the point is they are there, you can tease them with the mouse, they just don't display what they ought to. So please investigate this further.
Created attachment 37826 [details] System tray working when compositing is turned off with a white background
I am seeing the same behavior. This is on a clean Arch install with: kde 4.3.2 qt 4.5.3 ATI M6 on radeon 6.12.4 driver Compositing on All behavior is exactly the same as Michael reported. In addition though, the following scenarios show the icons correctly: 1. When the Widget Dashboard is brought up with ctrl-F12 (or any other method), the icons appear correctly, they distort again when the Widget Dashboard is exited 2. When compositing is turned off with alt-shift-F12, the icons change to black boxes, bringing up the Widget Dashboard makes the icons display correctly, then after exiting the dashboard they display almost correctly. The icons are visible, but they are each on top of a grey box (see atachment), it is very visible with a white background.
I confirm this on up-to-date Arch with KDE 4.3.2, xf86-video-intel 2.8.1 and qt 4.5.3 with compositing on.
it's a graphics driver bug, apparently icons won't be visible on windows with ARGB disaled, and only with some graphics drivers -could- be resolved on latest Qt tough
what is the status of this in a newer kde with a newer qt? i'm closing this for now. thank you
(In reply to comment #5) > what is the status of this in a newer kde with a newer qt? i'm closing this for > now. thank you Regretfully I moved away from KDE since then. Yes, it was because of this and other pains in the ass. But you can always try it out yourself.
I still can see this on up-to-date Arch Linux with KDE 4.4.4, Qt 4.6.3, xf86-video-nouveau 0.0.16_git20100517 with compositing off, at least for Klipper and Ibus icons.
Closing for lack of feedback.
