When I use truesky within ue4.25.1 on 4k monitor, the rendering picture only shows on the left-up side of the screen, where the other side is black. This problem happens on ue4.25.1.
The problem aready happened on UE4 editor. When I use 4k monitor, open editor , press Ff1, the probelm appears.
have you tried changing resolution scale (in UE4 scalability settings). Sometimes, TrueSky bugs out for me at 100% res scale on my uwhdmonitor (21:9), and im required to drop res scale to 99% for it to render full screen instead of 100% where it only renders a small portion on the top left.
Bug has been present in UE4 4.24 and 4.25
Thanks for your answer. I have found a solution: https://simul.co/question/weird-screen-clip-when-maimize-play-in-editor-selected-viewport/
