Example of wrong rendering

Open attached document in version 6.3 and in version 6.2. You need to double-click the formula and you need to set 'Original size' to get the actual rendering.

I have used a colored background, so that the size of the formula is better visible. The error remains, if you use the default transparent background.

The formula has additional space after the brackets and large additional space after the formula. I see the same error in Draw, but not in Writer.

I have used Version: (x64)

When I open  the sheet and click to open the OLE formula, it opens into sm with the width expanded to the box holding the OLE object--but the formula is clipped in its frame.  And if I select and try to move/resize the bounding box for the OLE object's frame--the size of the object then shrinks to a size smaller than what is shown initially for the layout of the formula in its cell.
Comment 3 V Stuart Foote 2019-02-06 07:49:28 UTC
But, not so clear about the regression, as I get the same off size behavior with with same system--with or without OpenGL rendering.
Comment 4 V Stuart Foote 2019-02-06 07:52:29 UTC
Another thing that is odd, is that there is no response to a <Ctrl>+Z, or entry in the undo history when the OLE being moved.

I'm not sure it's regression
Comment 6 Aron Budea 2019-06-04 22:36:44 UTC
Seems the same in 3.3.0 / Ubuntu 18.04. Let's say it's not a regression.

Comment 8 Regina Henschel 2021-06-04 08:46:11 UTC
The wrong size is in the formula in config-item-set ooo:view-settings in settings.xml. So the current rendered size corresponds to that setting. If you change to edit mode and change something, the size is not adapted and the formula is stretched into the old size. Only 'Orignal size' will repair it then.
Other way round, if you first  set 'Original size' and then go to edit mode, the area of the formula will be displayed with scrollbar although 'AutoUpdate display' is checked.

So there is still a problem how the hosting Calc application communicates with the embedded OLE.

Tested with Version: (x64) / LibreOffice Community
