skype tray icon detaches from witray after some time #228

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Run witray
2. Run skype
3. Wait for some time (I don't know exactly how long)

What is the expected result? What do you see instead?

The skype tray icon somehow detaches itself from witray and appears at the 
top-left of the X root window.  Clients in the managed area can obscure it.

What version of the product are you using (wmii -v)? On what operating
system (uname -a)?

I switch between my 24" desktop monitor and my laptop screen often using

simultaneously.

Below is the output of xprop on the detached skype icon.  It is interesting 
that wmii still sees the detached icon as part of witray (wmiir read 
/client/.../props says "witray:witray:witray" whereas xprop says 
WM_CLASS(STRING) = "skype", "Skype").

Also, I run skype under a different (less priviledged) user account and allow 
it to display on my X session via `xhost +local:` command.  Perhaps witray is 
treating the skype tray icon differently because it comes from a foreign user?

Hmm, I may have caused this bug due to a misconfiguration.

My /rules file previously had:

  /^witray:witray:witray$/ -> !

I just updated it to the new format:

  /^witray:witray:witray$/ tags=/./

I'll see if the bug still occurs tomorrow.

The bug still occurs.  Changing my /rules to use "tags=/./" did not help.

Did you try without any rules for witray? I don't understand why you need this 
rule.

Thanks for your suggestion.  I'm now trying witray without a rule; will report 
back if the bug occurs.

I just saw a similar thing with Opera's tray icon. When trying to respawn 
wmiirc (see current thread on the mailing list), the icon went to the upper 
left of the managed area and stayed there even after killing witray.

The bug still occurs with skype after I removed the witray rule.  I concur with 
comment 7.

Respawing wmiirc launches a new witray. If Opera doesn't support 
attaching to tray managers spawned after it launches then it's 
likely a Qt bug (Opera and Skype both use Qt to my knowledge).

Thanks, that makes sense, and gives me a workaround to the problem:

  pgrep witray || witray &

Only run witray upon wmiirc respawn if it's not already running.

Closing this issue.

The odd thing about this is that Skype seems to work fine for me 
if you replace witray by launching a new instance, but not if 
you forcibly kill the old one first.

Nevermind. Seems pretty hit or miss either way.

GoogleCodeExporter commented 8 years ago 
I found a problem with my workaround:

When my screen resolution changes (switching from laptop screen to external 
monitor), the wmii bar will not expand to fit the larger resolution unless I 
restart witray.

And upon restarting witray, I lose the skype icon just like before. :-(

Have you tried revision b3911f39ceda?

Original comment by maglion...@gmail.com on 20 Sep 2011 at 3:22

GoogleCodeExporter commented 8 years ago 
Yes, that revision helps a little bit, but doesn't solve the problem entirely:

1. Start witray.
2. Start skype and wait for its icon to appear in witray at the right-most end.
3. Run witray.  Observe that skype icon is still attached, but its position 
moves from the right-most end to the left-most end of witray.
4. Run witray again.  Observe that skype icon is detached.
5. Repeat step 4 a few times; no change in observation.

Thanks.

Well, the order that tray icons appear in is undefined. 
Unfortunately, it looks like if another tray manager is not 
available the instant the old one dies, Qt destroys its old 
window, creates a new one, and completely breaks its XEmbed 
implementation in the process.

Original comment by maglion...@gmail.com on 20 Sep 2011 at 5:34

GoogleCodeExporter commented 8 years ago 
Ah. It appears that I have this backwards and Qt's system tray 
implementation is more broken than I thought.

1) It doesn't actually implement XEmbed at all, it just relies 
   on system tray managers not caring. My last hack worked 
   around this bug.

2) If a new system tray owns the selection when the old one 
   dies, it attaches to the new one, but never selects 
   StructureNotify events from it. It only decides that the old 
   system tray is dead when it receives a destroy notify event, 
   which it only gets if it's selected the StructureNotify mask. 
   It completely ignores MANAGER messages if it doesn't think 
   the old system tray has died, so if a new system tray is 
   running when the old one dies, it'll associate with it, but 
   never disassociate from it.

*So* if you kill the old witray before launching the new one, 
you're golden... I'll see if I can work out a hack for this. 
Ugh.
