MacOS 15.1 - Mouse Click and Drag Issues

[dayvough]

Your system information

• System information from steam (Steam -> Help -> System Information) in a gist:
• Have you checked for system updates?: Yes
• Are you using the latest stable video driver available for your system? No, just fresh upgraded to macOS 15.1 from 14
• Have you verified the game files?: Yes

Please describe your issue in as much detail as possible:

Every time that I click and drag-select my hero and surrounding units, only 1 out of 3 or 4 drags will successfully happen. The others will be as if I just moved my mouse.

This actually happened even before upgrading to macOS 15.1 on 14.*

Steps for reproducing this issue:

1. Click a spot on the map
2. Drag select a group of units and make a box (think Starcraft selecting groups of units)

For more context I’m with my laptop closed and on an external Dell s2721dgf set to 2560x1440 @ 120hz.

I am seeing this in ARM M1 MAC as well.
