From kwin Wed Jul 29 16:37:29 2009 From: Radu Benea Date: Wed, 29 Jul 2009 16:37:29 +0000 To: kwin Subject: [Bug 201912] New: screen corruption when using effects (OpenGL and Message-Id: X-MARC-Message: https://marc.info/?l=kwin&m=124888550119570 https://bugs.kde.org/show_bug.cgi?id=201912 Summary: screen corruption when using effects (OpenGL and XRender) Product: kwin Version: unspecified Platform: Compiled Sources OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: NOR Component: general AssignedTo: kwin@kde.org ReportedBy: radub82@gmail.com Version: 4.3.00 (KDE 4.3.0) (using Devel) Compiler: gcc (Gentoo 4.3.3-r2 p1.2, pie-10.1.5) 4.3.3 OS: Linux Installed from: Compiled sources Happens to me here with KDE Version 4.3.00 (KDE 4.3.0) (svn 4.3 branch) and Gábor Lehel which uses trunk. Doesn't happen only to decorations but other windows as well, like in the screenshot at http://www.imagebin.ca/view/3pdvDd.html I can make more screenshots if needed but they all look very similar, although sometimes nothing at all is rendered and plasma from below can be seen instead of the missing portion, but when that happens and I run ksnapshot, the window is re-rendered correctly before the screenshot is taken. This is quite hard to reproduce under normal conditions but I found that it happens a lot more when the system is under heavy load (at mine it started happening much more when the load factor was greater than 2) and when notifications keep arriving while switching desktops or moving around windows. Another observation is that I never noticed this for small windows (less than half my screen size). This seems to be related to desktop effects and I could very easily reproduce it with both OpenGL an XRender and gave up after 10 minutes trying to reproduce it without effects. ( while trying to reproduce I kept my system under a average load of approx 6 and made sure I will get many notifications during this time ) Before you dismiss this as a driver or X problem please take into consideration that I use an ati (r300) card with radeon driver while Gábor Lehel uses an intel card as for X mine is 1.6.2 and his 1.5.2, also we both started experiencing this after updating kwin from svn recently, and this did not happen before. -- Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ kwin mailing list kwin@kde.org https://mail.kde.org/mailman/listinfo/kwin
