With Workspace.PlayerScriptsUseInputActionSystem set to Enabled, it is no longer possible to move the camera when the mouse is hovering over a BillboardGui with a UI element (button or frame) with Active set to true.
This happens in both first and third person. The billboard guis must be parented to playergui for this to happen.
This does not happen with player scripts use IAS disabled.
yeah this is definitely an engine regression with the new IAS. Active = true is aggressively sinking the camera drag delta when it’s parented to playergui, even if ur just hovering.
temp workaround: just set Active = false on those billboard ui elements if u don’t strictly need them to block clicks, or just keep IAS disabled for now. staff will have to patch the internal camera scripts for this. good catch with the repro file tho.
