Description 2016-05-01 15:17:25 UTC
Windows 7, LO  and LO


1. Use an existing document (or make a document with some text on top and two lines further down. 

2.  Scroll down, so that the two lines are visible, but not the top line.
(may have to adjust window size)

3. Set cursor on one of the bottom lines.

4. Click Clone formatting icon in Toolbar

5. When I move the mouse back to the document, the screen jumps to (almost) the top of the page.  (There are variations in what happens, but the critical point is that the screen view changes.)

6. Click off the Clone formatting icon  (i.e., without using the format).

7. Screen view returns to the original.

Expected behavior:  The screen should not change position when moving the mouse over the document, after clicking the Clone Formatting icon

Perhaps this is a "feature"?  It seems that when "clone formatting" is chosen, then the document position can be changed on the screen with the mouse alone. 
I would expect in "clone formatting mode" that the screen to remain stable (as when the normal cursor is set), and any positioning done with the slider bar.

Repro, except step 7 does not happen for me.

Problem (or feature) still present.

Still a problem with:

New (better?) description.

1. Use a file that has more lines than can be shown in the window.

2. Set the cursor in the window (where that are lines above the cursor that are not visible in the window).

3. Select "Clone formatting"

4.  Use the mouse.

5.  Notice that it is possible to scroll up and down (and left/right if the window is small enough).

In my opinion, this is a bug  (because it makes it more or less impossible to use the clone formatting, because the canvas jumps around.

As described before, the window should remain stable, unless the slider bars are used.

6.  Do not use Clone formatting, but unselect it.  The window returns to where the cursor was originally set.  (If you have scrolled up in the file, then it will jump back to where the cursor is)  (This is probably how it should be.)

The basic problem is still that mouse movement scrolls the canvas up and down (or left and right if the window is more narrow than the width of the document), when "clone formatting" is selected.  

Also, if the cursor is set on a line that is close to the top (or bottom) of the screen, then after selecting clone formatting, the screen jumps several lines (to move the line with the cursor away from the top (or bottom).
