Description David Smith 2022-03-29 14:37:07 UTC
Description:
Background Colour Malfunction in LibreOffice Calc

MALFUNCTION 
Background colours randomly disappear & reappear, in random cells

CAUSE
Loading an image to background (Menu-Format-Arrange-To background)
whilst using
Value Highlighting (Menu-View-Value Highlighting)

CONCLUSION
Value Highlighting cannot be used if an image is in background

Steps to Reproduce:
1. LibreOffice Calc-File-New
2. Select a decent block of cells
3. Click Paint icon arrow-Select a colour
4. Select a cell in the block
5. Menu-Insert-Image (locate and open an image from a directory)
6. Whilst image is selected, Menu-Format-Arrange-To background
7. Scroll to a new section of worksheet, and scroll back 
   The colours should be stable, as expected
8. Activate Menu-View-Value Highlighting
9. Scroll around, as before, to see colours disappearing in random cells
   (displaying erratic behaviour) 

Actual Results:
Random appearance, and disappearance, of background colours 

Expected Results:
The worksheet should display background colours correctly


Reproducible: Always


User Profile Reset: No

COMMENT
This BUG is bad news for any developer, because:
Value Highlighting provides at a glance knowledge of the worksheet
and
Background Colours provide at a glance knowledge of the worksheet
Both would normally be used together.

Using images as background may be required, or aesthetically pleasing.
As a background, values can be written over the images (very useful).

Background images, background colours, and value highlighting should be capable of working together.

ods file: BUG- Background colour fail when graphic sent to background AND Value Highlighting switched on

This is a simple ods worksheet.
Some cells have a background colour.
Some cells have a background image.

To recreate the bug, simply scroll around with Value Highlighting ON and OFF.

The background colours become unstable with Value Highlighting ON.

Thanks m.a.riosv for taking a look at this bug.
What are your thoughts on it's priority?

I ask out of interest rather than desperation.
I can live without value highlighting, though it is obviously better to have it.
It's a useful tool :)
