mouse cursor stutter while IPR

[kay vonlanthen]

hello chaos team
not really an issue just a "whyt is going on" question. here is a video to an thing i come across frequently when using the IPR in maya 2025 and win 10.
video shows the cursor having these weird studders. im unable to select objects. i think vray caches something in the background and cant catch up with the selection you are trying to do. can we fix that or do something to resolve this?

Make sure this option is checked

Did Twist 's suggestion help? Does it happen in a simple scene? The video is no longer available (sorry for the late reply). Is it a heavy scene?
