Description Mauro Calzavara 2020-06-22 10:57:06 UTC
Impress: When formatting a text box with a scrolling enhancement, the scrolling is normal in editing mode. But, when going to presentation mode (F5), the characters of the string reverse (first char becomes the last, and viceversa).

Steps to Reproduce:
1. Open a IMPRESS section
2. Add a single line Text Box
3. Apply the scrolling format to the text
4. Go in presentation mode (F5)

Actual Results:
The scrolling reverses from editing to presentation mode

Expected Results:
No reverse.

Reproducible: Always

User Profile Reset: Yes

OpenGL enabled: Yes

Fine in LO 7.1+ master with Skia, fine in old LO 6.1, not seen in Linux for me. 
Bug seen with GDI and OpenGL in LO 6.2 in Windows. So Windows bibisect needed. 
I know 3 good people doing it, let's add one one them here. 
Telesto, your info is useful, but is not complete, you need to pinpoint LO version where bibisect can be done, if you cannot do it yourself.
