Created attachment 189576 [details] example to show grayscal bug that turn some text to white color Since Libreoffice version between 7.3 and 7.5.5, when you want to **print in grayscale, some text in text frames disappears.** You can see on preview. In fact, those texts become white. Not all text are affected. Colored and black & white show all text. Libreoffice 7.3 doesn't show this problem. Windows and linux versions 7.5.5, 7.5.6, 7.6 show this problem. Regards
Created attachment 189577 [details] picture to show grayscale printing that turn text white
It seems to be related to 1st line of paragraphs. When you insert a space character at the begining of paragraph, the bug disappears, the text retrieves its "normal" color when printing in grayscale.
I bibisected the disappearing phenomenon with linux-64-7.5 repo to d5c8b38eab3d3766f403a33e11dffa498655be8f tdf#152990 set the font after the MapMode is (potentially) set Originally committed to 7.6 with b008831a5545e5a777d77547ef96b9798d795f30 In 24.2 the automatic text colour in the blue rectangle changed to white and it stays white in the print preview. This changed with ddb483509113e469b771320fea52f1b089574021 Resolves tdf#156182 - Automatic text color unreadable with darker cells
Resolved the contrast issues from bug 156182 with https://gerrit.libreoffice.org/c/core/+/158024 (new contrast applies to all colors but Light Blue 2 aka Tango Sky, which is the default for object background). But likely unrelated here.
But, when I set text color to black (for example), I expected it to be black.
Created attachment 193855 [details] A simple reproducer for Bug 157240 This FODG allows to reproduce easily (at least on Windows), by exporting it to WMF, and opening in a WMF reader like MS Paint. The text (black in the top box, yellow in the bottom box) arrives white. But the WMF shows as expected, when opened in Draw.
