Screen shot of the incorrectly rendered result
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Does this still happen with Qt 4.5.x and current KDE? Yep, the sample attachment still shows the bug with current Qt (4.5.0) and KDE (4.2.3). Well, let's rebase to F11 then (not Rawhide because that one has 4.3, so maybe it's fixed there already... we can always hope ;-) ). Is this still an issue with 4.3? -- Steven M. Parrish - KDE Triage Master - PackageKit Triager Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers Don't know, I don't have access to a system running KDE 4.3 and probably won't for at least a few weeks. it's still effacted in 4.3.1. It's great if someone could report this to KDE upstream (component: kstyle). thanks Ok reported upstream. Going to close this report in favor of the upstream one. -- Steven M.

Created attachment 324546 [details] Sample code to show the bug Description of problem: When the Oxygen style is being used, transparent backgrounds for widgets are not handled correctly. Undesirable artefacts are shown and transparency is not always enforced. Sample code is attached and I'll also attach a screen shot shortly. Using any other style works as expected, so the problem seems to be restricted to the Oxygen style. I have had correspondence with Nokia on this issue and we agree that the Oxygen style appears to be the cause. Version-Release number of selected component (if applicable): The bug only shows up for Qt4.4.1 and later. When using Qt4.4.0 the bug does not seem to show up. How reproducible: See attached code sample and screen shot. Actual/expected results: The sample code should show a light green box with QLabel text drawn over it. The bug instead causes a dark green box to be drawn partly over the light green box and the label never appears. Other manifestations of the bug show a black box instead, but the general behavior seems to be that a darker box seems to cover approximately the upper half of the widget and transparency is mishandled.
