Hi Telesto,

I've installed 6.0.0.1 linked. The situation got better in a sense, that I can
navigate between slides, and may exit the presentation. But the presentation is
still sluggish and the responsiveness is lagging. Toggling OpenGL and hardware
acceleration doesn't have any effect on the symptoms. When running the software
in safe mode the symptoms stay exactly the same. Openoffice-4.x provides smooth
experience in comparison on the same machine. There is a difference, that OOo
swaps the two monitors and puts the presentation preview on the other.
I use only the default extensions, which includes Hungarian dictionary.
I can reproduce the problem on multiple Win 7 Enterprise 64bit machines at my
workplace (this particular has Q9400 with 8Gb of RAM) and on a laptop that has
i7-4900MQ and 32Gb of RAM, running Win 7 Pro 64bit.
Should I capture a video about what is happening or the description is enough?
