When you move your mouse cursor to open or close tabs in Google Chrome, you may say a big black shade in the background. It does not affect the function, but it really bothers me.
If you have the same issue and do not like it appear again, please see below for details:
Step 1: Open Google chrome, and click the setting icon (3 dotes) on the top-right of the screen;
Step 2: Click "Setting" from the drop-down list;
Step 3: Move down to the page bottom, and click "Advanced";
Step 4: In the new window, move down to bottom again, and disable "Use hardware acceleration when available";
Step 5: Click "Relaunch", the black shape should disappear now.
