Image display control can't get last event when in snapshot mode

Hello,

 

There are many overlays on my image display control, and when the image is quickly updated, the overlay will flickering. I changed the image to snapshot mode as provided in the link below,  the flickering problem is solved.

However, in snapshot mode, the Get Last Evnet method encountered an exception. When I click on the image control, there will be no Click Event generated. The attached vi can see the problem.

ps. I'm using LabVIEW 2020

 

Thanks

Henry
