Take a look at the video above. It shows TweakSoftware’s RV experiencing this horrid effect. I’ve also had Maya experiencing similar behavior. Random white flashing for a millisecond or two, just enough to be noticable and very, very annoying! But only in a handful of applications, all sharing a similar GUI framework, Qt. But I never encountered a similar issue in Nuke, for example. It seemed to be related to VSync in the GPU drivers or Windows drivers somewhere, however, after exhaustively testing and ruling out one possible cause after another, I finally found out that the problem was Logitech’s old mouse drivers!
I never paid too much attention to my Mouse and Keyboard (both from Logitech) drivers as they simply worked from day one so I kept on installing the same, aging, version. However, after finally uninstalling and installing the latest SetPoint drivers, I finally got rid of this irritating problem! Both RV and Maya now behave as advertised!
Unfortunately I wasn’t able to find any more concrete information about this issue, but I bumped into a few programming forums discussing VSync issues and Logitech’s mouse drivers, which lead me to try reinstalling them with the current version.
So, if anyone out there suffers similar problems and has no idea how to get rid of it, try uninstalling Logitech’s drivers.
