As the title says, my mouse cursor flickers in XCOM 2 when Crossfire is enabled. I am running Windows 7 Ultimate (SP1) with 16GB DDR4, 2x HD7790, and a core i3-6100, using Crimson 16.3.2 (it also flickered in 16.3.1). None of the textures or other graphics are noticeably flickering, just the mouse cursor, and it's flickering speed seems to increase and decrease along with the frame rate.
The character of the flicker seems to change (regularity and speed of the flickering) when I mess with the AA settings, but nothing else has seemed to effect it at all. Any ideas for what else I can try to get rid of the cursor flickering?
