Description of problem: 1. Scrolling on the title bar no longer activates titlebar wheel events. 2. The window buttons no longer have the minimize, maximize, help, close &c markings. Version-Release number of selected component (if applicable): qt-4.8.0-0.1.tp.fc15.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
The titlebar wheel event is back! I don't know whether the update to kde-4.6.4 cured it, but I can scroll on the titlebar to make he window opaque again. The window buttons are still all the same. They remain undifferntiated, so one cannot tell which is which.
> The window buttons are still all the same. They remain undifferntiated, so one cannot tell which is which. I can confirm this for 3 other machines. Two different Fedora 15 machines and one Fedora 14 machine all running qt-4.8.0-0.1.tp.fc15.i686 / KDE 4.6.4.
I just updated to kde-4.6.90 and the titlebar scroll effects no longer work.
(In reply to comment #3) > I just updated to kde-4.6.90 and the titlebar scroll effects no longer work. I just had this discussion a week ago on the fedora lists: in gnu linux one does not need to reboot. Oh, no. The problem is that I didn't run needs-restarting. Or, in a graphical environment, one has to log out and back in. Well, I ran needs-restarting and it showed that nothing needs restarting after having updated to kde-4.6.90. Then, to be sure, I logged out and back in. Then, I wrote the last comment. I just did a cold boot, and guess what? titlebar scroll effects *do* work and the symbols on the window frame are there again. So, one does need to reboot for some updates to take effect.
Issues are still there, but masked. KDE 4.7 seems to detect Qt 4.8 and adjust accordingly, enabling the Raster (software) backend and trying to disable as much as possible the Native (hw accelerated, at least in theory) backend. Those glitches are produced by the Native backend, buggy in Qt 4.8. You can easily see the lack of symbols on the window frame and other glitches if you run: kwin --replace --graphicssystem native & You'll see more glitches appearing in all apps using Oxygen if you start them with --graphicssystem native in Qt 4.8, regardless of your KDE version (scroll arrows are missing, some gradients are rendered incorrectly, tabs have thick 5px lines). So, this seems to be a Qt bug, and it is not fixed with Qt 4.8 Beta 1.
Thanks for the analysis, it's probably time to upstream this to bugs.kde.org at least.

https://bugreports.qt.nokia.com/browse/QTBUG-20542 The KDE bug report was CLOSED as UPSTREAM, so, I upstreamed the bug report.
I notice, upon upgrading to kde-4.7.0, that titlebar scroll effects do not work, while the button symbols do appear.
Interesting conversation on #kde-devel today, [08/14/11 18:26] <maelcum> what eare the current problems with kde on qt 4.8? [08/14/11 18:26] <maelcum> s/eare/are/ [08/14/11 18:46] <rdieter_laptop> maelcum: so far, mostly just http://bugs.kde.org/show_bug.cgi?id=278478 (that I'm aware of...) [08/14/11 18:46] <bugbot> KDE bug 278478 in Oxygen (general) "Rendering glitches with Oxygen and the Native graphics system with Qt 4 8 " [Normal,Resolved: upstream] [08/14/11 18:46] <thiago> native is just broken [08/14/11 18:46] <thiago> use raster [08/14/11 18:47] <sreich> don't we have rendering issues every qt release? :) [08/14/11 18:47] <maelcum> rdieter_laptop: thanks. i'm using raster anyway.

Re comment #11 Please file a separate bug, though I'm not sure what fixes/debugging we can do for users of nvidia's binary blob driver (I cannot reproduce any such crashes using intel hardware, fwiw)
ah, I can reproduce some sort of crash now to, actually trying to use krunner, will file a bug myself.
