Issue:
Camera movement becomes noticeably less smooth when panning by moving the mouse cursor to the edge of the screen while any unit or building is selected.
If no units or buildings are selected, edge scrolling is smooth. However, as soon as any unit or building is selected, the camera briefly micro-stutters while panning.
It is more noticeable on high-refresh-rate monitors. I’m currently playing on a 300 Hz monitor with G-Sync, V-Sync, HDR, and VRR enabled, and the camera micro-freezes are very noticeable on the monitor once they occur.
Repro Steps:
-
Start any match.
-
Ensure that no units or buildings are selected.
-
Move the mouse cursor to the edge of the screen to pan the camera.
-
Observe that camera movement is smooth.
-
Select any unit or building.
-
Pan the camera again by moving the mouse cursor to the edge of the screen.
-
Observe the micro-stuttering during camera movement.
Expected Result:
Camera movement should remain equally smooth during edge scrolling, regardless of whether units or buildings are selected.
