Thanks for sending that over, it looks like that's the CoreTemp app window. We are aware of this issue, but it's not something we can fix on our end. We reached out to the devs at CoreTemp to see if they can fix it up, we'll let you know if we hear anything back.

Thanks! ]]> https://www.displayfusion.com/Discussions/View/small-white-window-appears-and-disappears-on-mouse-move/?ID=c44c97fe-7852-4816-828b-55ddad7d8e7f#3 Wed, 10 May 2023 20:53:19 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/small-white-window-appears-and-disappears-on-mouse-move/?ID=c44c97fe-7852-4816-828b-55ddad7d8e7f#3 DisplayFusion Owen,

Thanks for your reply.

I've attached the video ]]> https://www.displayfusion.com/Discussions/View/small-white-window-appears-and-disappears-on-mouse-move/?ID=c44c97fe-7852-4816-828b-55ddad7d8e7f#2 Wed, 10 May 2023 18:53:11 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/small-white-window-appears-and-disappears-on-mouse-move/?ID=c44c97fe-7852-4816-828b-55ddad7d8e7f#2 DisplayFusion Hi Paul,

Could you send me over a video of the issue? ]]> https://www.displayfusion.com/Discussions/View/small-white-window-appears-and-disappears-on-mouse-move/?ID=c44c97fe-7852-4816-828b-55ddad7d8e7f Wed, 10 May 2023 11:32:06 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/small-white-window-appears-and-disappears-on-mouse-move/?ID=c44c97fe-7852-4816-828b-55ddad7d8e7f DisplayFusion I'm running Display Fusion Pro 10.0 on Windows 11

For the past few weeks, every time I move the mouse after awhile, I see a small white window that appears... and the mouse is frozen during that period. The window flash is in the upper left hand of the monitor.

If I turn off DisplayFusion this doesn't happen.

Does anyone know what this could be? ]]>
