Anyone else experiencing this strange issue? If I sit still in space or docked in a station/citadel, I pretty reliably get 30-40 FPS, but just moving the mouse around causes it to grind almost to a halt, although the FPS indicator claims it sits at around 13 FPS or so. The weird thing is that I do NOT get a drop in FPS if I click and drag - only moving the cursor on its own causes the issue. I have cleared my cache from the escape menu, deleted my wine folder from ~/Library/Application Support/EVE Online/p_drive/Local Settings/Application Data/CCP/EVE/SharedCache and experimented with different graphics settings (fullscreen, fixed window, windowed mode, and all the various quality settings) and the issue persists. This only just started today - was playing for several hours yesterday with no issues. Any advice would be appreciated!

EDIT - issue went away after I toggled back and forth between fullscreen, windowed, and fixed window a few times. Not sure what the root cause was but it seems to have done the trick.
