We've seen an issue with some mobile cards (like yoru K1100M) exhibit this.
Try forcing the graphics processor to be the nVidia processer in the nVidia control panel. See attached imaged.
- Right click on empty part of desktop
- Choose "NVidia Control panel"
- Choose "Manage 3D Settings" on left
- Choose "High Performance NVIDIA processor" for "Preferred Graphics Processor"
Let us know if this works.
Just a follow up that the team here has been able to isolate the cause of this and a proper fix should be in the next service pack (sp 2.0)
Thanks! The "Preferred Graphics Processor" solution did not work (I usually keep the default processor to the NVIDIA), so will keep an eye out for SP2.
