If you have a unit selected and it moves the camera will follow. Is that what you mean?

I'm on a desktop and I've had the same problem. I've even watched it scroll so far to the left that I can't see the map anymore until I click and it snaps back to the left edge of the map as if it detected I was trying to scroll to far. But then it would continue to scroll back off the map. After a while (a minute? maybe two) it stopped doing it and worked correctly.

Sounds like this is some lagacy bug from GalCiv 2.

I can't be certain that their reusing code from GalCiv2, but it would be logical for them to reuse code if not broke rather than discard it without justification. Keep an eye on this bug, I thought this bug was squashed long ago. I rather like it to be dealt with sooner rather than later.

Also - I just exited to the main menu and started a new game without exiting the program and the slow map shifting is still occurring.

Yeah I have a lot of scroll bugs, like others have posted.  Not scrolling, scrolling when I'm not at edge for a bit, scrolling a little in a random direction when not at edge, and scrolling in the wrong direction all together when at edge.

Same issue here on a desktop.  Click drag or edge of screen scroll to stop it.

Gunna chime in with seeing this bug as well.  The map likes to float sometimes for me in different directions, although a quick scrolling in and out seems to fix it.

While we're on the topic of scrolling, does pushing the cursor to the edge of the map to move it not work for anyone else?  If I want to see different sections of the map I have to zoom out and then zoom back in to the location I want to be at.  When trying to scroll with the edges it'll only move in one direction (like using the top left corner will only move me very slowly to the left, no up movement) or just not move at all.

EDIT: Found the answer in the bug compilation thread, looks like it's not even in game yet <.<

I have the same bug but am on a desktop using a laser mouse...it mostly seems to happen during building placement for me, though.

I've also had this problem.  I've seen similar bugs when a Mouse up event is lost because the player starts to drag in one area, but lets the mouse up inside a GUI element, so the map never gets the mouse up event that says 'stop panning'.  Don't know if that's what's happening here, but the symptoms are similar.

I also have this bug from time to time. As mouse scrolling isn't offically implemented yet, I think it will be cleared up once it has.

I have noticed this bug as well.  I have discovered the steps to reproduce it.  I'm posting them here so we have a record of them for whoever gets assigned to fix this.

Also, the testers can attempt the repro steps and verifiy that it reproduces for them as well.

Steps:

1. From main map, move mouse to around the center of the screen

2. Push down and hold the middle mouse button,  while holding down the button, move the mouse to the right side of the screen.  This will rotate the camera, but when the mouse is at the edge of the screen it will start to scroll.  Once it starts to scroll, stop moving the mouse and hold at that point. 

3. Without moving the mouse, let go of the middle mouse button.

The map will now be stuck in scrolling mode, even if you scroll the other way.

Sometimes I can get it to snap out of the auto-scroll bug by rotating the camera and moving the mouse near the edges while I do so.

Can others verify this reproduces the problem?

This has happened to me as well but it's not sliding to the side it's sliding up as well. It's slid up four or five times on me while sliding down only once or twice.
