In your case, there is something wrong with the system. First of all, it is recommended that you don't open other programs, especially browsers, when playing full-screen games, which will easily lead to program errors and conflicts. Look at the following methods in other aspects:

1. You right-click to open the properties of Warcraft launcher, select compatibility, check the last three items in the setting box, and then check the special permissions.

2. If not, use 360 security guards to quickly scan Troy to see if there are any missing system files, then clean up the garbage with one click, optimize again, and finally choose system repair.

3. If you can't do it, delete Warcraft completely, go to the perfect hard disk version under the Pacific Game Network, and then install it on a different disk (never install it on the C disk). Don't pack it too deep (that is, a folder is a folder). It is best to install it in the root directory of the disk. Don't name the folder of Warcraft in Chinese, otherwise it is easy to make mistakes.

4. Furthermore, the system has been used for a long time, various settings have been changed too much, and the program is easy to conflict or make mistakes, so the system can only be reinstalled. In fact, as long as the garbage is cleaned up and optimized at ordinary times, it is generally no problem not to install the software indiscriminately.
