--- Comment #38 from Patrick Luby <[email protected]> --- (In reply to Patrick Luby from comment #37) > Here's a diff that you can use to reproduce the bug by spinning the scroll > wheel while pressing the Shift key. Open an empty spreadsheet, > Shift-scrollwheel 5 to 10 times, then release the Shift key and scrollwheel: One more data point: with my patch in comment #37, if I swipe horizontally I can get to the column furthest to the right and immediately vertically swipe without any problem. This makes me think that the idle timer is waiting for the maximum column number to be added to the visible columns and the idle timer is just getting overwhelmed by the number of visible columns to add. Since swiping makes significantly larger jumps than a scroll wheel triggers the bug but making the jump ridiculously high does not, I think that there is some jump range that creates significantly more new visible columns to add and so it just takes forever for the idle timer to plough through adding all those columns. Whereas when you can jump to the end of the columns with a handful of swipes, maybe the idle timer only needs to handle a few hundred visible rows in total? -- You are receiving this mail because: You are the assignee for the bug.
