Mac client triggering CMD+(key) upon entering a new map when tabbing to separate client
Summary
When multi-clienting, if one character enters any map that triggers a loading screen, if you quickly tab to another client via CMD+` it acts as if the CMD key is being held down. For example, if F4 is pressed when this happens, where my Blessing key is on my priest, it acts as CMD+F4 and closes that client altogether. If I press the E key and no other button, my inventory opens up.
Steps to Reproduce
- Move one character to any other map that triggers a loading screen.
- Quickly tab via CMD+` to another client, specifically noted when done quickly, upon seeing the screen fade out or the very beginning of the loading screen.
- Press any key on the client that gets tabbed in, and the effect remains even after pressing any amount of keys.
Additional Information
This does not happen 100% of the time, and as stated, happens mostly when the second client is tabbed in almost immediately. Running Sierra OS currently, and the same problem occured with Yosemite.
