I tried to record the screen, but I found that the delay became less noticeable when I was recording. When I turned off the screen recording software, I dragged the box with the mouse, the mouse arrived first, and the box reached the mouse position One third of a second later. Moving the box with hotkey G will not delay. I am sure that replacing other versions of the graphics card driver will not help.

Oh, think of it, I took the process with the phone.

it's wired! I found that when I play the movie at the same time, there is no delay at all, and there will be a delay after closing the movie!

The video was compressed.

Thx for getting back, this sounds very much like T61474.
(issue there seems to be that hardware acceleration gets wonky using gizmos -- and seems to be less of an issue when other GPU accelerated apps run next to blender)

@zhang net (netzhang79): I will merge these reports, but feel free to comment again if you are also having issues without the gizmo active (I see running the mediaplayer [another GPU accelerated app] solves the problem for you, too...)

Not related to the 3d program. Running other 3d software at the same time will still cause delays. Currently there is no delay in recording video and playing video.
