Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
It displays crazy black artifacts on my system when I enable triple buffer:
See #44301#319037
Windows 7 Enterprise 64 Bit SP1 on a Intel Core i7-4800MQ, AMD Radeon HD 8790M / Intel HD Graphics 4600, Blender

@Psy-Fi, think you're the expert in this area. Could be a video driver problem tho.
Looks like a driver issue. Might be some option in the driver settings even. But I highly doubt it's an issue on our side.
Think getting opengl32.dll from http://download.blender.org/ftp/sergey/softwaregl/ and placing it next to blender.exe will give us clue if it's video driver issue or not.
This dll will make blender to use fully-software opengl, which is free from driver-related issues, but it makes blender slower.

Well yeah.... Really slow with the software opengl dlls but no flickering any more... So thanks for your time, folks.
These dual graphic cards are just not supplied with good quality drivers. And no one can help, I bet. (well, AMD and Intel and the computer manufacturer might, but they won't...)
You might want to file a report with Intel they do have a forum here https://software.intel.com/en-us/forums/graphics-driver-bug-reporting, but if your laptop has locked drivers from manufacturer then you will have an issue..
