[gentoo-user] Heads up: KDE 4.3 does *not* work OK with Qt 4.6

[gentoo-user] Heads up: KDE 4.3 does *not* work OK with Qt 4.6

[Nikos Chantziaras]

I read on various blogs (especially Gentoo-related :P) that "KDE 4.3.4 
works just fine with Qt 4.6".

If you were about to upgrade, spare yourselves some headaches.  It does 
not work "just fine."  On first sight, it does seem to work, but if you 
look a bit better, it does not.  Symptoms of using KDE 4.3 with Qt 4.6:

   * Logging out of KDE takes half a minute.
   * Amarok takes ages to load.
   * The text on (Oxygen) push buttons is not centered.
   * Fonts and shapes appear somewhat messed up (e.g., the tray clock).
   * Global shortcuts (like CTRL+ESC to start "System Activity") stop
     working after a few hours of uptime.

There might be more, but I didn't stay around long enough to find out. 
I reverted to Qt 4.5.  Note that I *did* a full rebuild of all packages 
that depend on Qt, including all of KDE of course ("equery depends" is 
your friend).

Bottom line, KDE 4.3 *does* work with Qt 4.6, but it does *not* work 
"just fine" (there's a big difference between "works" and "works fine").

Well, it does. For me.

Maybe, didn't measure the time.

Yes.

It is here.

Not here. Tray clock sometimes messed up with TQ 4.5, too.

Works fine here, even after days of uptime.

And there's also a big difference between "works fine for me" and "works fine for 
you", it seems ;)

I assume you mean 'x11-libs/qt' or could you be more specific?

nope.

bottom line your system is screwed and you think it is qt4.6

What would be the other Qt, then?

You don't need to measure anything to tell the difference between 3 
seconds and 30 seconds :P

OK.

Look closer.  But you would need Qt 4.5 to compare...

*Never* happens here with 4.5.  With 4.6, it's *always* wrong.  Again, 
you need 4.5 to compare.

Usually happens when starting programs that register new shortcuts. 
Like Amarok or Mumble.

Probably.  But you confirmed some of the problems.

One last thing I forgot to mention in my OP: The X process was using 
800MB of RAM after 5 hours of uptime.  "Desktop Effects" are enabled, by 
the way.

x11-libs/qt-*  They all go together (you can't mix versions.)

Plain x11-libs/qt is deprecated.

If it got screwed, certainly not by me.

emerge -e world

retest, compare, post results. No other way to be sure.

Apart from long logout times (more likely firefox as that's the last visible 
window to close; and/or skype and opera) I do not experience any of the 
troubles you report. But I had an emerge -e world in between merging qt-4.6 
and now (courtesy of patch)
