Description:
I have two spreadsheets:

1) "Textbox foible 0.ods" has one sheet containing some tables, a chart and a Textbox which is linked to a cell.

2) "Textbox foible 1.ods" has two sheets: the first has the same tables as in the Textbox foible 0.ods and the second contains the chart and Textbox.

When I open "Textbox foible 0.ods" and add a new value in column B the Textbox updates and then flickers rapidly. Resmon shows soffice.bin using 25% of the CPU.

When I open "Textbox foible 1.ods" and add a new value in column B the Textbox updates but does not flicker. Resmon shows soffice.bin using 0% of the CPU.

I hope that this helps,
Mike.
I will try to attach the two spreadsheets to this report but, in case that doesn't work, I have put the two versions of the spreadsheet in my Dropbox; you can find them here:

Steps to Reproduce:
1. Open "Textbox foible 0.ods" and add a new value, say 80, to cell B8 - press enter.
2. Take a look at the Textbox just below the X axis and you will notice it flickering.
3. Do the same for"Textbox foible 1.ods" and you will notice that the Textbox, which is on sheet "Jan chart" is not flickering.

Actual Results:
Flickering in case 2. of "Steps to Reproduce"

Expected Results:
_No_ flickering in case 2. of "Steps to Reproduce"


Reproducible: Always
