Screenshot of slideshow not working

When I start slideshow by F5, I cannot see the slides, only scrollbars appear on the sides of the screen (see attached screenshot). I'm using fglrx driver.

Disabling hardware acceleration fixes the issue for LO 4.3, but LO 5.0-dev crashes on slideshow start (see attached trace)

I confirm immediate crash after clicking start slideshow with hardware acceleration disabled

Windows 8.1 x64

LibO 5.1.0.0.alpha1+
Build ID: 8d46bc15e93687f93d7c85064acc71231e2f08b1
TinderBox: Win-x86@39, Branch:master, Time: 2015-06-02_05:16:07
Locale: en-US (it_IT)

however if hardware acceleration is enabled I can start slideshow though I cannot exit it correctly... see Bug 91574 - SLIDESHOW: presenter console not shown and crash on exit

Same result, but I can exit ok when hw accel. is enabled.

I can confirm exactly same issue on Debian 8 (jessie):

Version: 5.1.0.0.alpha1+
Build ID: a64999511ae654131d997eec9a3d78478cfc1c75
TinderBox: Linux-rpm_deb-x86_64@46-TDF, Branch:master, Time: 2015-06-22_05:01:17
Locale: es-ES (es_ES.UTF-8)

LibO crashes after disabling hardware acceleration.

Enabling HA starts the presentation (with presenter console) but got bug 91574
Comment 5 Carlos Rodriguez 2015-07-09 14:48:29 UTC 
Seems to be fixed on Debian 8 (jessie):

Version: 5.1.0.0.alpha1+
Build ID: 85ce6a2446deb0f4c01604b6188f969603de9b16
TinderBox: Linux-rpm_deb-x86_64@46-TDF, Branch:master, Time: 2015-07-09_02:29:43

and

Version: 5.0.0.2.0+
Build ID: 991dd34d66dada90de0f5eb8f28deb74af8c5851
TinderBox: Linux-rpm_deb-x86_64@46-TDF, Branch:libreoffice-5-0, Time: 2015-07-09_08:22:48

Thank you!!

Well, let's set to WFM.
Original reporter should test with the freshest builds to confirm that they are seeing the same as Carlos.
Comment 7 g4827387 2015-09-16 21:04:45 UTC 
I confirm that it works with the latest RC - no crash anymore.

(though hw acceleration does not work on slackware for some reason - http://www.linuxquestions.org/questions/showthread.php?p=5385277)
