I recently built a PC using a Radeon R9 290 GPU, OS Windows 8.1. Searching online for the GPU drivers lead me to AMD Catalyst 13.11 Beta 9.4 for Windows. While going through the install process everything seemed fine until the drivers themselves installed. The screen went black for a few seconds (as the program said it would) and when it came back everything was fine except my mouse pointer had somehow enlarged to a comical size.
At first I thought my mouse settings had been changed by the install, but when I went into settings Windows 8.1 was under the impression I was still on the default smallest mouse size. Changing mouse sizes simply resulted in the pointer becoming even bigger. Multiple reboots didn't fix the issue ither. My mouse pointer was the right size on the user logon screen but enlarged on my profile. I then tried switching between screen resolutions but the pointer was still enlarged on all settings. Uninstalling the drivers solved the issue, but whenever I reinstall the same thing happens.
Notes: Am using HDMI input for the screen running through the GPU. When the mouse pointer enlarges, it becomes pixelly as well like a low-res image blown up. While searching the issue found an old Catalyst mouse pointer problem but that appears to be a different effect to this one. The rest of the screen stays at the same size and resolution it was before the install, only the mouse pointer gets distorted.
Would appreciate any ideas on what to try next, at a loss atm.
