Description jvight.extra 2017-07-14 13:25:38 UTC
When Windows 10 is set to a High Contrast theme, text will show as black with a black background when opening a new Impress project. This makes editing and creating new text impossible.

However, if you go to Tools -> Options -> LibreOffice & click the "Application Colors" option... a short pause will occur & magically all the text in the Impress slides will turn to white & be readable.

I need to do that workaround every time I open Impress to work with the application. It appears as if Impress isn't properly detecting High Contrast mode & updating the text colors until I select "Application Colors" from within the Options menu.

LibreOffce is setup to detect High Contrast / Accessibility in options.

Steps to Reproduce:
1. Enable High Contrast mode in Windows 10
2. Open a new Impress Document
3. Try to add some text -- it will be black on black (unable to see)
4. Go to Tools > Options > LibreOffice > Application Colors
5. Watch text magically become white & readable

Actual Results:  
The text becomes white as expected, after initially being black (the bug that needs fixing).

Expected Results:
Text should be readable on application start. High Contrast mode should be detected & black on black should be fixed on application start -- not requiring selecting "Application Colors" in the Options menu.

Reproducible: Always

User Profile Reset: Yes, and it made the problem worse. The workaround "Application Colors" didn't help, because I presume "Detect Accessibility" was unchecked or perhaps "Use Automatic Colors" was different.

Repro already in 4.4, but not in 3.5. Maybe I should try to bibisect later.

For testers: to enable High contrast, search for High contrast in the menu in Win 10.

Unfortunately we only have Windows bibisect repos to 4.3 branch point and the bug already exists in Version:

=> NAB but duping to bug 112739

Setting is found with the Accessibility settings. To avoid the workaround, and use the HighContrast DE settings in LibreOffice:  

Open Tools -> Options -> Accessibility and in the Options for High Contrast Appearance block, check the "Automatically detect high contrast mode of operating system" AND/OR the "Use automatic font color for screen display"

That will pick up the colors from the HC themes.
