Description Massimo 2017-10-10 06:25:35 UTC
Description:
When using hardware accelerator, the top row of pixels is not shown in screenshow. After turning it off, the overline is sometimes (not always) missing in screenshow. Examples in the attachments.
- overline_bug.odp: a single-slide presentation;
- overline_bug.pdf: the PDF created from the presentation (everything is fine);
- with_hardware_acceletator.jpg: screeshot of the slideshow obtained with hardware accelerator turned on: look at the capitol letters, for example: the top-line of pixels is missing; 
- without_hardware_acceletator.jpg: screeshot of the slideshow obtained with hardware accelerator turned off; some of the overlines are missing, look at the points around the central one (the big one), and compare them with the odp or pdf file.

Steps to Reproduce:
1. Turn on hardware accelerator, run slideshow 
2. Next turn off hardware accelerator, run slideshow 


Actual Results:  
Pixel missing in slideshow 

Expected Results:
Correct showing in the slideshow 


Reproducible: Always

Not reproduced with 5.4.1 or 6.0, but I am running Win 10 in a virtual machine.

Maybe try with 6.0 to be sure: https://dev-builds.libreoffice.org/daily/master/Win-x86_64@42/current/
It installs separately.

Set to NEEDINFO.
Change back to UNCONFIRMED, if the problem persists. Change to RESOLVED WORKSFORME, if the problem went away.

Just checked with 6.0.5.2, the bug seems fixed.
