Hi HenryVIII,

I am not experiencing or seeing any issues on this end. Can you take a screen shot of the issue you are experiencing? Also, please post a copy of your dxdiag in order for us to be able to test on comparable hardware.

Thanks,

Hi

It’s hard to screen this problem, actually all context menu do not showing. I click on right mouse button and got nothing. In fact, a menu “appears” and if I blindly move the cursor and press the left button will be selected some of the menu items. In material and blueprint editor I got this. Same things with Epic Games Launcher.

Some menu appearing when I reducing size the editor window.

My dxdiag
