currentDamage()

QRegion KWin::VirtualEglGbmLayer::currentDamage ( ) const

overridevirtual

Implements KWin::OutputLayer.

Definition at line 86 of file drm_virtual_egl_layer.cpp.

queryRenderTime()

std::chrono::nanoseconds KWin::VirtualEglGbmLayer::queryRenderTime ( ) const

overridevirtual

queries the render time of the last frame. If rendering isn't complete yet, this may block until it is
