Debian 11发现一个bug，Xwayland cpu 100%
重现过程：
登录
1. 打开一个终端（其它一些程序也可以）
2. 拖动终端窗口，鼠标指针碰到屏幕边缘，松开。
Xwayland cpu使用率100%,如下：
进程号 USER PR NI VIRT RES SHR %CPU %MEM TIME+ COMMAND
1413 john 20 0 1071740 59244 39136 R 100.0 1.5 0:06.20 Xwayland
3. 此时，鼠标仍可使用，关闭终端窗口，图形界面将彻底卡住，不能使用。
这种情况经常出现，其它操作也可能会出现这种情况。
硬件环：vmware虚拟机。
