Struggling to find recipy, but already happened 3x in the morning while trying to merge changes from Phil's review:
1. Open math manual, go to the second table in 3.7 2. Open new window 2, open new file and starting to reproduce the formula 3. ctrl+m ^19 4. unclear sequence of these: a) backspace to delete 19, or type something again b) zoom in/zoom out c) switch to different window/workspace (the immediate crash trigger seems to be always when activating LyX window after wandering elsewhere) It seems that cursor size and geometry gets sometimes wrong unless I start typing and things go immediately right. But sometimes it crashes. (is MathData::dimension dependent on zoom level?). I am not even sure that the first window is necessary, but it might be related because the zoom in/out changes the geometry in the first window as well... Instant preview is on. Will try to come up with better backtrace, but this is what I have now: CoordCache.cpp (25): break on pointer: 0x560af36eb560 hint: dim size: 0 ( 1) src/lyx: lyx::doAssertWithCallstack(bool) ( 2) src/lyx: lyx::doBufErr(char const*, char const*, long) ( 3) src/lyx: lyx::lyxbreaker(void const*, char const*, int) ( 4) src/lyx: lyx::MathData::dimension(lyx::BufferView const&) const ( 5) src/lyx: lyx::InsetMathGrid::cellXOffset(lyx::BufferView const&, unsigned long) const ( 6) src/lyx: lyx::InsetMathGrid::draw(lyx::PainterInfo&, int, int) const ( 7) src/lyx: lyx::InsetMathHull::draw(lyx::PainterInfo&, int, int) const ( 8) src/lyx: lyx::RowPainter::paintInset(lyx::Row::Element const&) const ( 9) src/lyx: lyx::RowPainter::paintText() ( 10) src/lyx: lyx::TextMetrics::drawParagraph(lyx::PainterInfo&, long, int, int ) const ( 11) src/lyx: lyx::TextMetrics::draw(lyx::PainterInfo&, int, int) const ( 12) src/lyx: lyx::InsetText::draw(lyx::PainterInfo&, int, int) const ( 13) src/lyx: lyx::InsetTabular::draw(lyx::PainterInfo&, int, int) const ( 14) src/lyx: lyx::RowPainter::paintInset(lyx::Row::Element const&) const ( 15) src/lyx: lyx::RowPainter::paintText() ( 16) src/lyx: lyx::TextMetrics::drawParagraph(lyx::PainterInfo&, long, int, int ) const ( 17) src/lyx: lyx::TextMetrics::draw(lyx::PainterInfo&, int, int) const ( 18) src/lyx: lyx::BufferView::draw(lyx::frontend::Painter&, bool) ( 19) src/lyx: lyx::frontend::GuiWorkArea::paintEvent(QPaintEvent*) ( 20) /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5: QWidget::event(QEvent*) ( 21) /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5: QFrame::event(QEvent*) ( 22) /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: QCoreApplicationPrivate::sendTh roughObjectEventFilters(QObject*, QEvent*) ( 23) /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5: QApplicationPrivate::notify_ Pavel -- lyx-devel mailing list lyx-devel@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-devel
