when i using two different monitors as dual, run in window mode on one monitor
Drag the window to the opposite monitor and move it to the full screen,
The window breaks strangely and the entire UI is distorted.
At this time, the UI on the monitor side does not respond,
Only the broken UI on the other side is mouse-clicked.
how can i solve this problem?? the version is 4.20.3
that drag-to-other-monitor distortion is mixed DPI — when you drag and go fullscreen, cached primary display size is used for Slate pointer transform so secondary scales wrong. fix is per-monitor size (Window->GetFullScreenInfo().GetSize2f()) or BP-side GetDPICorrectedCursorPosition which recomputes per-monitor scale.
