Hi,
In my case I’m using the arrow keys since it’s easier for me to reproduce the bug with them. Otherwise yes, I’m talking about the editor viewport. This problem doesn’t seem to occur while In PIE or Standalone game.
I’m more or less able to reproduce this problem, unfortunately I don’t have any way to visually record my keyboard and my screen at the same time. What I can add is that I’m using a wireless keyboard, but I have it since the Rocket beta 2, so I don’t think the problem come form it.
I can guarantee that under the same hardware configuration but with the build 1711197 (beta 3) I don’t met this problem.
