After my last Windows update, several applications started showing weird behavior, namely the text cursor had acquired a tendency to wander left during typing, making accurate typing impossible. I managed to track down two causes:
1. My gaze was resting somewhere near the bottom of my primary screen, and
2. The Tobii “Windows snap assist” feature had to be enabled.
Turning off snap assist made my system behave normally again.Windows version: Windows 10 Pro Insider Preview, build 17035

Could you kindly be explicit in which software you were running when the text cursor was moving (ie Chrome, Word, etc)
The cursor would not move if you were looking toward the top of the screen is that correct?
Also, I assume you are running the latest version of the Tobii Tracking Software?Thanks for the details, we will try to and squash this bug as soon as possible.
15/11/2017 at 17:26 #7594twentythreeParticipantAs far as I can tell, I’m running the latest Tobii software, at least I get no updates when I check for them. I posted the precise versions above.
It doesn’t seem to matter what window I’ve focused, I’ve reproduced this in Firefox, Notepad, the Windows start menu, Windows settings, Tobii settings, Explorer, etc.
A low level keyboard hook (WH_KEYBOARD_LL) shows me injected keyboard events (flags: LLKHF_INJECTED, vkCode: 37, scanCode: 0; as opposed to regular inputs that have a scanCode set), most likely sent by Tobii software.
As for when exactly it happens, refer to the following screencast – it also seems to depend on what’s in the background: http://download.tiitoo.com/screencasts/2017-11-15%2017-09-20.mp4In case it doesn’t reproduce for you, did you try this on a Windows Insider Build?

We should hopefully have some news for you soon.

The latest version available (June 2018) is v2.13.3 and can be download @ https://gaming.tobii.com/getstarted/?bundle=tobii-core
Please kindly update to the latest version and let us know if you still have any problems.
Thanks,
