Hi I am using the newest version of Maya 2018 and the Malcolm animpicker has been giving me this issue where its icons are all blown up and impossible to work with. I've been trying to troubleshoot this for hours now with no luck. Has anyone experienced this issue in the past and know of a solution?

Yeah I ran into that this week. Its due to maya's UI scaling and possibly your general resolution. Check in your maya preferences under the Interface category. At the bottom of that category it should have a interface scaling. Play with those options (have to restart maya for them to take effect) and you should be able to fix it, however your maya Ui will probably be really tiny :/

Best of luck!
