Snowflake symbol != WYSIWYG in prints and as exported PDF file

Steps to reproduce:

1. Go to https://www.compart.com/en/unicode/U+2744 and copy the red snowflake symbol in the clipboard
2. Paste it into LibreOffice Writer -> a shaded blue snowflake appears
3. Try to print or export it as PDF
4. Printed document and the PDF lacks the blue snowflake

Attached you can find a screenshot how it looks in writer.
Prints or PDF exports don't show the blue snowflake.

Comment 2 Julien Nabet 2023-06-28 08:14:35 UTC
On pc Debian x86-64 with master sources updated today, I could reproduce this.
(gtk3 and gen renderings)

There's no specific console log.
Comment 3 mgruber 2023-06-28 09:08:36 UTC
I'll attach the ODT and an exported PDF of it.

I used Firefox to copy into the clipboard an im on XFCE as desktop environment - not sure if that makes a difference.

This a regression in master/7.6, thanks for catching it. It is fixed now.
Comment 8 mgruber 2023-06-30 08:02:35 UTC
Will this also fix the printing or just the PDF export?
Comment 9 ⁨خالد حسني⁩ 2023-06-30 08:20:42 UTC
Printing in Linux typically uses PDF so it should work. It will not work when using PostScript for printing.

On pc Debian x86-64 with master sources updated today (ce391e52fbb759997f7e2c225513cc074a0f3974) + brand new LO profile, I've got now the snowflake when exporting in pdf but it's black. Shouldn't it be blue (like in Writer) ?

Indeed! With Firefox, the snowflake has the right color!
Thank you Khaled!
