fixedSize()

std::optional< QSize > KWin::EglGbmCursorLayer::fixedSize ( ) const

overridevirtual

For most drm drivers, the buffer used for the cursor has to have a fixed size. If such a fixed size is required by the backend, this function should return it

queryRenderTime()

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

overridevirtual

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