            Bug ID: 113714
           Summary: Flicker when hovering over main menu with default
                    rendering
           Product: LibreOffice
           Version: 5.0.0.5 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Keywords: bibisected, bisected, regression

Opening this as a fresh start for the original issue in bug 105863, without the
interference of bug 112486. When checking for this issue, disregard any LO
version between 5.3.2-5.3.6 and 5.4.0-5.4.2 because of that reason.

- Switch to default rendering.
- Start Writer.
- Move mouse over main menu.

=> The menu flickers.

It's Windows-only, and possibly depends on hardware/drivers.
Occurs for me with default rendering both with an AMD RX 570 GPU and an Intel
HD Graphics 4000 IGP (in i7-3520M CPU). Does not occur with OpenGL enabled.

Reproduced with 6.0 daily build (2017-11-06_23:18:19), 5.3.0.3, 5.0.0.5 /
Windows 7.
Not reproduced with 4.4.0.3.
=> regression

Flickering has started with the comment referenced below. Adding Cc: to Tomaz
