Q:無法點擊物品欄中的物品

A:You need to change the Resolution.Turn it up, the exact value you need to try yourself...

You can use the dichotomy method:

If you are now at 50%, you can try adjusting to (50%+100%)/2=75%,If it still doesn't work, you can adjust to (75% + 100%)/2=88%.

This is the fastest way to do it, while your resolution is not modified too much.
