I am on a 32bit pc running Windows 7 enterprise and just installed f.lux but now my mouse cursor is flickering. Has anyone else seen this?
I haven't seen this reported yet, but I think a possible solution is enabling Pointer Trails via the Registry so that we can make it look like they're not even enabled.
What you do is, you navigate to HKEY_CURRENT_USER\Control Panel\Mouse. Then, double-click "MouseTrails" in the right-hand pane and change its value to either -1 or 99, and then log out of Windows and log back in. They should both have the same result, but try both just in case one is better somehow.
If this doesn't fix it, then I wouldn't know what else to recommend.
