--- Comment #6 from Tyler <[email protected]> --- OK, I've built a new test document and checked again with a fresh profile and my real user profile. A) With a fresh profile, I see the effect only when moving between non-table text and tables. When the cursor moves into (or out of) a table, the context-sensitive table toolbar pops up (or vanishes), this causes a size change of the document canvas, which in turn triggers the (delayed) jump of the viewport. If I turn off any context-sensitive toolbars, this doesn't happen. B) With my real profile, I have all toolbars off anyway and see this jump nevertheless. Turns out that the open sidebar (even with all panes closed) is the culprit! So, to summarize: A is explainable and probably expected behavior, given the (IMHO debatable) way the full-page view mode works. But B is a bug I would say: UI elements should trigger canvas resize events only if the size actually changes. Re comments #2, #3: I don't see any dependence on the single/multi/book view. Smooth scroll seems to slow down rendering a bit (noticeable only at unreasonably small zoom, i.e. many pages to render), but otherwise no change. The updated repro instructions are then: * Load attached document * Set View->Zoom->Entire page * Enable the sidebar (View->Sidebar) * Put the cursor on a normal, plain text paragraph in the middle of a page. * Scroll down half a page using the mouse wheel. The gap between pages should be in the middle of the screen. * Move the cursor up (with arrow keys) until you touch the table or down until you touch the paragraph with reddish background. -- You are receiving this mail because: You are the assignee for the bug.
