Last bet: the screen is constantly been redrawn. lyx -dbg debug and then loading Johns document without actually touching it triggers a flood of the following message on the console: void BufferView::Pimpl::update(Update::flags)[fitcursor = 0, forceupdate = 2, singlepar = 0] buffer: 0x869db58 ViewMetricsInfo BufferView::Pimpl::metrics(bool) npit: 58 pit1: 0 pit2: 0 ViewMetricsInfo BufferView::Pimpl::metrics(bool) y1: 0 y2: 2149 Redraw screen void BufferView::Pimpl::update(Update::flags)[fitcursor = 0, forceupdate = 2, singlepar = 0] buffer: 0x869db58 ViewMetricsInfo BufferView::Pimpl::metrics(bool) npit: 58 pit1: 0 pit2: 0 ViewMetricsInfo BufferView::Pimpl::metrics(bool) y1: 0 y2: 2149 Redraw screen void BufferView::Pimpl::update(Update::flags)[fitcursor = 0, forceupdate = 2, singlepar = 0] buffer: 0x869db58 ViewMetricsInfo BufferView::Pimpl::metrics(bool) npit: 58 pit1: 0 pit2: 0 ViewMetricsInfo BufferView::Pimpl::metrics(bool) y1: 0 y2: 2149 Redraw screen etc. until I kill LyX. Why is this? Jürgen
