When using the DualSense controller it appears the touchpad is incompatible with emulating mouse.

Examples:

Left mouse button:

1. If I try to drag-and-drop an ability by holding L3 and moving the touchpad, the 'hold' stops working as soon as I move the touchpad.
2. If I want to click something by moving the cursor with my touchpad and pressing L3 then the first L3 click doesn't work, only the second one does. This repeats every time I use the touchpad to use the cursor, if I use the right stick to use the cursor then L3 works first try every time.

Right mouse button:

• Whenver I press R3 after moving the touchpad it just resets the cursor to the middle of the screen, without detecting the click. As above, no such issue when using the right stick to move the cursor.

The only way I can use the touchpad with right/left click is if I use the tap-to-click setting, but it only works on left OR right button, so whichever option I use the other mouse button will still act as described above.
