With my p4, I have to resize the window to less than 1/4 of the screen to make the problem go away. A standard performance tip for LyX is a smaller screen size. I presume LyX redraws the entire window on every key press? Would that be easy to change? It seems that LyX should only have to redraw the current paragraph, and often only have to redraw the current line. > Anyway, not really a realistic use-case :-). > > With your thesis, I can see slowness only when causing a scroll up and down > of the document (this is already evident [and annoying] with the UserGuide), Good idea. The User Guide probably makes a better example document than the background chapter of my thesis. > otherwise movements don't seem slow if the cursor simply moves on the > visible screen without causing any scrolling. Cursor movement can be slower than the typematic rate on this P4. > Also disabling on the fly spell-check and instant preview doesn't help. Same here. -- John C. McCabe-Dansted
