example odp of the bug

When using Impress to present an odp file containing RTL text on Windows, It is at best displayed in LTR directionality and at worst completely messed up.

I tested on Linux and Windows (both with LO The bug only shows up on Windows. On Linux everything is rendered correctly as far as I could tell (which is misleading when making and testing a presentation on Linux to present on a Windows box).

Attached is a simple example file of the bug.

Note that it does not matter on which platform the presentation is made, it will display incorrectly on Windows, and only in full-screen presentation mode.

Hello Shimi,

Thank you for reporting the bug. I can confirm that in slide show mode the arabic is not shown correctly in 4.3.3.

Seems like this bug is fixed with the new renderer in 5.3.
