In KDE 4.1 beta 2, I have a similar problem with pulldown boxes. The shadow is displayed before the actual contents of the pulldown widget. FYI, I'm using a NVidia geforce 6600 with NVidia drivers (a pretty fast GPU for desktop effects). Can anyone still reproduce this bug with a recent KDE version? (4.1.3 / 4.2beta2 / 4.2svn) and updated graphic drivers ? Thanks :) Still reproducing it on 4.2 beta with a GeForce 8400gm, beta drivers (180.08). It will be visible in any situation when the system is under load. It does not look like a driver issue to me, just a synchronization problem (but the fact that the system is so often under heavy load with a recent nVidia might be a driver issue!). Not sure if kwin is guilty though... maybe it is just a QT thing. still reproducing the problem: intel cards (2.5 drivers) kde 4.2beta2, xorg 7.4 (xorg-server 1.5.3) same problem here nvidia 8600gt, driver 180.22 kde 4.2.0 Problem still exists in KDE 4.3.1. The desktop doesn't feel good with that. ... and in KDE 4.4.4. (Using the intel xorg driver 2.12.) In 4.6 development, with a radeon 300, and looking carefully, the shadow appears after the window is displayed (tested minimizing and restoring without any other effect). Also tested calling krite, looking, closing, looking... May be my eyes are not fast enough, but I do not see. Are you able to reproduce it with a more recent KDE SC version (4.5.2 or later)? I am running daily trunk and can still confirm the bug. This is especially visible when browsing menus (for example the traditional kickoff). It is important to know that we have to different shadows: 1. The "classic" shadows used for undecorated windows or "legacy" window decorations (not Oxygen or Aurorae) 2. Decoration shadows which are more or less part of the window and only painted together with the window. The bug only applies for the first kind of shadows. If blur is also used it is difficult to say if the bug is still present as those two effects interfer. Given the architecture of our compositing stack I am rather sure that the bug is still present and fixing it probably requires some rework on the shadow effect. The biggest problem is not the "order" of compositing, but the fact that KWin happily renders the shadows even if the application has not used sync() or flush() yet to actually render the content. Git commit 3b8984d630cc6dc655a171fa9c0f7e74e9ee3c61 by Martin Gr����lin. Pushed by graesslin into branch 'graesslin/kwin-cleanup'. Remove Shadow Effect. The shadow effect is known to be broken since at least 4.5. It is unfortunately in a state which makes it difficult to maintain and the architecture has some serious drawbacks. Therefore it is the best solution to replace the effect with a new and better implementation. For more information about the new implementation please see the discussion on KWin mailinglist: http://lists.kde.org/?l=kwin&m=129607406517609&w=2 This also "fixes" all existing bug reports about the shadow effect. Most of the bugs will really be fixed when the new shadow system is implemented, if not it is a new bug and a new report should be created for it. Please excuse that we go this unnormal approach to mark bugs as fixed with code removal.
