Firefox tabs look malformed

[laughingLoki]

Binary package hint: gtk-qt-engine-kde4

Ubuntu 8.04
gtk-qt-engine-kde4 1.1-0ubuntu1

It looks as though the tab image is being painted again at the bottom of tabs in Firefox. I would expect the tabs to look the same as those in Konqueror. I've attached an image comparing the two.

[Jonathan Thomas (echidnaman)]

Oh, crap. Sorry. I was a little bit to quick with the dupe hammer there... Sorry. :(

But, as far as the bug goes, this happened back in KDE3 with whatever style was being used there.

[_tek_ (tek-notes)]

Finally found the correct bug!

I can confirm Firefox tabs do not render correctly for me either when using gtk-qt-engine-kde4.

[Jonathan Thomas (echidnaman)]

Migrating to Intrepid package name.

[_tek_ (tek-notes)]

No backport for us Hardy guys?

[Jonathan Thomas (echidnaman)]

There's probably at least a chance that if a fix does get made in svn somebody'll backport it to the KDE4 ppa. Unless it's fixed after Intrepid is released.

the same issue in Kubuntu 8.10.

Generally, all the same issueS, as submitted there:

The bug only happens in case you have NVidia drivers.

[Vladimir Mityukov (mityukov)]

For me it happens with radeon driver (enabled by default in Kubuntu 8.10).
My card is X1600XT.

[Julien Aubin (gojulgarbmail)]

Tested on a laptop running the free ATI driver on a Radeon9700, with desktop effects, Kubuntu 8.10 and KDE4 and the issue could not be reproduced.
It occurs on all my three other computers, which run the proprietary nvidia driver.

[Julien Aubin (gojulgarbmail)]

Forgot to write, the driver I use on my Radeon9700 is the "ati" driver, not the radeon or something else. Don't know what the difference is.

ati is like a "meta-driver". It has radeon, and some other drivers (1 or two more). The correct one is picked then, basing off installed hardware. In your case it should be "radeon", like in mine.

And I definitely have this issue with tabs, along with some other issues, within pages themselves (specifically -- forms' controls and some other). Desktop Effects On and Off.

And the issue goes away, after selecting a "native" theme for GTK apps (like Clearlooks). I.e., it's only with "gtk-qt-engine" being used for theming Firefox.

I think more correct ;-)

P.P.S.: couldn't see the same issue e.g. in "Linux DC++" client. Probably, the issue is connected to Firefox's own "skin" as well. Have not tested.

[Julien Aubin (gojulgarbmail)]

Workaround :
- Kill firefox.
- Open the GTK-QT style config panel in system settings.
- Choose "use another font" if not selected, and click Apply
- Then click "Use my KDE fonts in GTK applications", and click "Apply"
- Restart Firefox
- The bug should have disappeared.

[_tek_ (tek-notes)]

Did as Julien suggested, with one twist...

Simply choosing "use another font" did not enable the Apply button. I had to first click to change which other font I wanted to use then I clicked apply. Went back chose to use KDE font once more and clicked Apply.

No change. Still have the crappy looking tabs.

I'm running Kubuntu 8.10 Intrepid KDE 4.1.2, nVidia FX550 with the nvidia 173.14 drivers. Although this doesn't really matter as I've also tried the ati (radeon), fglrx, and vesa drivers.

Also I'm noticing a new issue with rendering where having scrolled down a page buttons (command and option alike) seem only half rendered until I mouse over them. Nothing as major as the tabs, but a little annoying.

I found using an alternative firefox theme in the meantime helps, but you don't get that nice integrated look. But then again Netscape didn't give you that either.

[Julien Aubin (gojulgarbmail)]

Actually I noticed the workaround I provided needs to be redone at every KDE startup.

_tek_ -> did you kill Firefox before doing your manipulations and restart it after doing them ? I could reproduce the behaviour several times on my different computers and it seems to work.

"-".

[_tek_ (tek-notes)]

Sure did. In fact killed it before ever starting the process.... maybe a reboot will help (I'm a programmer by profession so I know the drill). However I think a reboot may fix it as when I initial installed the qt-gtk theme it didn't apply to any of the gtk apps until I rebooted, not sure which service it is that is providing this or I would just restart that.

I'll post back when I have a chance to do a reboot and let you know. Thanks!

P.S. -> Ouch I just saw what your first line says, every KDE startup? This bug still needs to be fixed, thats a hack, not even a workaround.

[_tek_ (tek-notes)]

Just realized if this needs to be done at each startup a reboot wont help. I shut down all mozilla apps (thunderbird and firefox) and continued to the fix as described one more time. Still no change. I'm not that worried about it as I'm using a different Firefox theme at the moment. I think I'll either wait for a real fix, or fix this myself and submit a patch when I have the time.

[_tek_ (tek-notes)]

Not that everyone wouldn't like it fixed ;)

[John Doe (sundaram-mailinator)]

exists on 9.04 as well.

A decent workaround is changing from QT4 look to QTcurves.

My tabs and scrolls look fat but are fully working

[dotancohen (dotancohen)]

I can confirm the issue in Kubuntu 9.04 with the open source ATI drivers.

The upstram bug moved from Trac to Google Code, here is the new issue:
http://code.google.com/p/gtk-qt-engine/issues/detail?id=44

[Jonathan Thomas (echidnaman)]

Sadly, gtk-qt-engine is a quite broken piece of software and has been removed from distribution. (See bug 404930)
Unfortunately this means that the large number of bugs will not be seeing fixes. :(

For now, the best integration option for KDE is the QtCurve style, (gtk2-engines-qtcurve) which offers a theme quite similar to the default Oxygen theme. The configuration module for gtk-qt-engine has been salvaged and is now living in the kcm-gtk package, which will be available and installed by default in Kubuntu 9.10.

Thanks for understanding. This package tried its best, but in the end did not live up to the standards required by anybody who doesn't like looking at a broken Oxygen imitation.
