[Solved] Tooltip colours impossible to read

[kingfisher]

Hello. This issue arose after I installed 4.1.6. Previously, when I hovered the mouse over a hyperlink (in cell to which a cell style applies) the tip was quite readable. Now it is in a white font over a light blue background as shown by this snapshot. The snapshot enlarges what is seen and the tip text is readable here. The colours are the issue.



Is there some way to change the colours? I find nothing in Tools > Options > OO > View, Appearance or Accessibility.

There is no button, the cell has a cell style featuring a grey background, an outline and a shadow.

EDIT : It seems I wrongly blamed 4.1.6 for the change. See post after next; a change in the GTK2 theme was responsible.

EDIT : The problem applied to all tooltips and was an effect of the KDE colour scheme.

The tip I get has black text on a yellow background, similar to a note inserted with Insert -> Comment. Can you post a document?

Thanks, FJCC. It transpires that it is an effect of the GTK2 theme I use. Changing to the Adwaita theme fixed the issue in another GTK application (which alerted me to the possible cause) but not in OpenOffice. The themes BlueMenta and Menta give me a tip with white on a black background in Calc. Another aspect of the former is more appealing so I have settled on that.

It transpires that the issue applied to all tooltips and changing the Gtk2 theme was not the best solution. This is a KDE system and there is a system setting to apply colours to "non-QT applications." That setting has to be disabled.
