几个月前，我遇到了UE视口卡顿以及掉帧的问题，一直没有找到解决的办法，并且使用了UE Insights，通过Trace片段发现卡顿同时 Pumpmessage峰值的现象，我在windows进程中找到了一款软件的快捷键调用导致了这一切，在结束该软件的进程后我解决了UE视口卡顿的现象。
A few months ago, I encountered problems with UE visual interface card and frame drop, but I have not been able to find a solution. Using UE Insights, I found that the phenomenon of both the peak value of the peak of the user’s Pumpmessage through Trace fragments, and I found a software shortcut key call in the windows process. After finishing the process of the software, I solved the phenomenon of UE viewing interface card.
