https://bugs.freedesktop.org/show_bug.cgi?id=30483 Summary: r600g makes kwin (ab)use 100% CPU Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/R600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: oyvinds@xxxxxxxxxxx 1. Use r600g as of today ("eselect mesa r600 set gallium" on Gentoo) 2. Enable desktop effects in kwin 3. kwin now uses 100% CPU doing.. who knows. I've tried disabling every effect in kwin, doesn't matter. Tried changing other settings also, makes no difference. kwin works fine with r600c. I started kwin, waited a while, it keeps on using 100% CPU forever so how long should not matter, and ran gdb kdm $pid. bt gave this: ------------------------------------------ (gdb) bt #0 0x00007fe94bb7101b in memcpy () from /lib/libc.so.6 #1 0x00007fe931000379 in util_copy_rect () from /usr/lib64/dri/r600_dri.so #2 0x00007fe9310020c5 in util_resource_copy_region () from /usr/lib64/dri/r600_dri.so #3 0x00007fe930f75c30 in st_texture_image_copy () from /usr/lib64/dri/r600_dri.so #4 0x00007fe930fac50d in st_finalize_texture () from /usr/lib64/dri/r600_dri.so #5 0x00007fe930fa1698 in finalize_textures () from /usr/lib64/dri/r600_dri.so #6 0x00007fe930f9e306 in st_validate_state () from /usr/lib64/dri/r600_dri.so #7 0x00007fe930f72885 in st_draw_vbo () from /usr/lib64/dri/r600_dri.so #8 0x00007fe930f97b64 in vbo_exec_vtx_flush () from /usr/lib64/dri/r600_dri.so #9 0x00007fe930f933c5 in vbo_exec_FlushVertices_internal () from /usr/lib64/dri/r600_dri.so #10 0x00007fe930f95212 in vbo_exec_FlushVertices () from /usr/lib64/dri/r600_dri.so #11 0x00007fe930e856e6 in _mesa_PopAttrib () from /usr/lib64/dri/r600_dri.so #12 0x00007fe94a4a5ca0 in KWin::PaintClipper::Iterator::~Iterator() () from /usr/lib/libkwineffects.so.1 #13 0x00007fe94a4b1a68 in KWin::renderGLGeometry(QRegion const&, int, float cons t*, float const*, float const*, int, int) () from /usr/lib/libkwineffects.so.1 #14 0x00007fe94bf0de18 in KWin::SceneOpenGL::Window::renderQuads(int, QRegion co nst&, KWin::WindowQuadList const&) () from /usr/lib/libkdeinit4_kwin.so #15 0x00007fe94bf121b4 in KWin::SceneOpenGL::Window::performPaint(int, QRegion, KWin::WindowPaintData) () from /usr/lib/libkdeinit4_kwin.so #16 0x00007fe94bf0303e in KWin::Scene::finalDrawWindow(KWin::EffectWindowImpl*, int, QRegion, KWin::WindowPaintData&) () from /usr/lib/libkdeinit4_kwin.so #17 0x00007fe94bf1b855 in KWin::EffectsHandlerImpl::drawWindow(KWin::EffectWindo w*, int, QRegion, KWin::WindowPaintData&) () from /usr/lib/libkdeinit4_kwin.so #18 0x00007fe94bf01f2b in KWin::Scene::finalPaintWindow(KWin::EffectWindowImpl*, int, QRegion, KWin::WindowPaintData&) () from /usr/lib/libkdeinit4_kwin.so #19 0x00007fe94bf1b955 in KWin::EffectsHandlerImpl::paintWindow(KWin::EffectWindow*, int, QRegion, KWin::WindowPaintData&) () from /usr/lib/libkdeinit4_kwin.so #20 0x00007fe94bf03a4c in KWin::Scene::paintWindow(KWin::Scene::Window*, int, QRegion, KWin::WindowQuadList) () from /usr/lib/libkdeinit4_kwin.so #21 0x00007fe94bf04f67 in KWin::Scene::paintSimpleScreen(int, QRegion) () from /usr/lib/libkdeinit4_kwin.so #22 0x00007fe94bf01f77 in KWin::Scene::finalPaintScreen(int, QRegion, KWin::ScreenPaintData&) () from /usr/lib/libkdeinit4_kwin.so #23 0x00007fe94bf1ba52 in KWin::EffectsHandlerImpl::paintScreen(int, QRegion, KWin::ScreenPaintData&) () from /usr/lib/libkdeinit4_kwin.so #24 0x00007fe94bf03c75 in KWin::Scene::paintScreen(int*, QRegion*) () from /usr/lib/libkdeinit4_kwin.so #25 0x00007fe94bf13d9f in KWin::SceneOpenGL::paint(QRegion, QList<KWin::Toplevel*>) () from /usr/lib/libkdeinit4_kwin.so #26 0x00007fe94befe87c in KWin::Workspace::performCompositing() () from /usr/lib/libkdeinit4_kwin.so #27 0x00007fe94be827c2 in KWin::Workspace::qt_metacall(QMetaObject::Call, int, void**) () from /usr/lib/libkdeinit4_kwin.so #28 0x00007fe94776fda6 in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) () from /usr/lib64/qt4/libQtCore.so.4 #29 0x00007fe94776c656 in QObject::event(QEvent*) () from /usr/lib64/qt4/libQtCore.so.4 #30 0x00007fe94838cecc in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /usr/lib64/qt4/libQtGui.so.4 #31 0x00007fe9483934cb in QApplication::notify(QObject*, QEvent*) () from /usr/lib64/qt4/libQtGui.so.4 #32 0x00007fe94b6cc0e8 in KApplication::notify(QObject*, QEvent*) () from /usr/lib/libkdeui.so.5 #33 0x00007fe94775cb0b in QCoreApplication::notifyInternal(QObject*, QEvent*) () from /usr/lib64/qt4/libQtCore.so.4 #34 0x00007fe94778957a in ??
