Minimap Snapping Glitch (Gameplay)

Recently I've been experiencing an annoying bug with the minimap where suddenly, and for no reason that I can find, my cursor controls the map fov without me clicking, instead of simply moving the cursor icon. Basically, my fov will move wildly around the rift until I left click the minimap and then space to re-center it on my champion. It is easily rectified, but can cause me to path incorrectly or lose sight of a teamfight for a split second. It occurs ~10 times per game and is really a pain. Thanks
