tested under Win8.1 x64 using LibO 4.4.3.2 and 4.4.5.1

I don't reproduce the issue either on a single or on a dual monitor setup.

all the 6 slides are correctly shown in the slideshow with no blank first slide.

please tell your O/S version 

then try resetting the user profile (backup first) following the instructions at this link: https://wiki.documentfoundation.org/UserProfile 

if the issue persists, please post a screenshot of the bug in action

P.S. edited summary notes with a clearer description

Unconfirmed with v4.4.5.1 under windows 7 x64.

Comment 3 mpredosin+libreoffice 2015-07-23 15:19:51 UTC

The problem still happens after removing %appdata%/LibreOffice and reopening the PowerPoint file on Win7 x64.  The first slide is blank and subsequent slides are corrupted in the slideshow viewer.  The slides show up correctly in the Microsoft PowerPoint Viewer.

Here is the specific OS version & build #:
OS Name:                   Microsoft Windows 7 Ultimate
OS Version:                6.1.7601 Service Pack 1 Build 7601
System Type:               x64-based PC

take a look at Bug 40534 - Slide tearing in LARGE screen with h/w acceleration enabled

your screenshots look like the ones from that bug

please tell your monitor model and resolution

probably it's a duplicate.

Graphics card: Nvidia GeForce GTX 780
Monitor:       Dell U3014
Resolution:    2560x1600

Comment 9 mpredosin+libreoffice 2015-07-23 15:44:58 UTC

The problem goes away when I disable H/W acceleration as mentioned in bug 72389.

Comment 10 tommy27 2015-07-23 16:58:25 UTC

exactly what I suspected... it's a duplicate.
