Random white flashes in application windows bug

Get the Flash Player to see this content.

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.


  1. I just started experiencing similar issues with the Autodesk application Maya 2011. Very annoying white flashes about every minute or so. After reading your blog I realized I had just installed a new Logitech keyboard and its drivers/ software “Setpoint.” I have not resolved the issue yet. Thanksfor your Blog.

  3. I have the same problem. I bought a new computer with AMD 8150 processor and AMD HD 7700 graphics and 4 GB or ram. I was so unhappy. I am going to uninstall the mouse driver right now and see the result.

  5. I didnt uninstall the Logitech Driver SetPoint but i went to it Mouse Game Settings and activated Game Detection, set it to OS implementation, Apply Game settings, clicked the keep r/l hand button and keypress assignments button. I no longer have the white flash. Good luck!

  7. Thank you so much!!! I have been experiencing this Maya flash every few seconds, sometimes a double flash and it’s been driving me nuts for the past few years. When I purchased my computer I also purchased an Anywhere MX wireless mouse and it’s my favorite mouse to date. I installed the software and thought nothing of it. Over the years I tried in vain to figure it out from online searches, to trying dozens of old video card drivers. I even purchased a Quadro video card thinking my ATI HD Radeon video card was the problem but when the flickers happened with the Quadro I then thought it was the motherboard.

    I got so frustrated with it on my PC I would stop working in Maya for months at a time until I really had to work again from home on a job. I made a video of the flash and it’s uploaded at youtube. In the youtube search field type: E62hKAAqzF8

    I usually searched for “flicker Maya” but last week I searched “flash Maya” and found this blog on top. After reading your article I immediately uninstalled the software and was skeptic but it stopped the flash. I was so relieved and could finally enjoy my custom built PC I hated all these years. After that I installed the most recent version of the Setpoint software and the flash is not present which tells me they fixed the conflict.

    Thinking back I remember there was a time the Maya flash was gone but eventually returned. I thought updating the video card driver caused it which I did do at the time. What happened was I noticed the updated versions of Setpoint were missing some customization features I liked for the middle button (also known as the application switcher). That’s why I went back to the original software that came with the mouse. So much trouble from a simple little thing.

    Thanks so much again for the article.
