Description ada 2025-05-27 17:59:01 UTC 
Description:
Themes do not work when Windows 11 high contrast mode is enabled, as all colors are defined by the High Contrast colors, even when attempting to change the LibreOffice theme. There should be a way to toggle this behavior.

Steps to Reproduce:
1. Enable High Contrast Theme in system settings

Actual Results:
All colors are defined by the High Contrast theme, even when attempting to change the LibreOffice theme.

Expected Results:
Allow for an override of the high contrast setting.


Reproducible: Always

Following os/DE HC theme provided colors is by design and intentional to meet accessibility needs.  Non-AT dependent users should simply not select a HC color theme in their os/DE.

IMHO => WF

In "Tools" -> "Options" -> "LibreOffice" -> "Accessibility", there is a "High Contrast" combobox whose value defaults to "Automatic". Does setting that to "Disable" give the result you want?

Yes, this does work. I apologize, I didn't know to find the setting as it turns out.

Sorry, I had forgotten about the rework [1] for bug 151522 providing user ability to toggle.
