Login from fresh new account, the problem persists.
Set OpenGLIsUnsafe = true, does not work.
Set compositing backend to XRender does not work.
Disable compositing does not work.

If start plasma-desktop from konsole, there are some garbage on the screen.
And console log stop at:

plasma-desktop(4851)/plasma SystemTray::DBusSystemTrayTask::createWidget:
plasma-desktop(4851)/plasma SystemTray::DBusSystemTrayTask::createWidget:
plasma-desktop(4851)/plasma SystemTray::DBusSystemTrayTask::createWidget:
plasma-desktop(4851)/plasma SystemTray::DBusSystemTrayTask::createWidget:
plasma-desktop(4851)/libplasma Plasma::FrameSvg::resizeFrame: Invalid size
QSizeF(0, 0)
plasma-desktop(4851)/kdecore (K*TimeZone*)
KSystemTimeZonesPrivate::instance: instance(): ... initialised
plasma-desktop(4851)/kdecore (K*TimeZone*)
KSystemTimeZonesPrivate::readConfig: readConfig(): local zone=
"Asia/Shanghai"
plasma-desktop(4851)/kdecore (K*TimeZone*)
KSystemTimeZonesPrivate::readZoneTab: readZoneTab(
"/usr/share/zoneinfo/zone.tab" )
plasma-desktop(4851)/libplasma Plasma::ExtenderItemPrivate::themeChanged:
plasma-desktop(4851)/plasma Clock::clockConfigChanged: showTimezone: false

Any idea?
