linuxqq占用大量xwayland连接客户端

我使用的os为cachyos，但之前使用archlinux时也有类似的问题，就是linuxqq这个包提供的qq会吃满所有的xwayland连接，导致其他需要xwayland启动的程序无法正常启动，如微信、steam游戏等，具体症状如下：

启动微信：

wayland连接数：

❯ xlsclients | wc -l

xlsclients: unable to open display ":0"

❯ xlsclients -al

256 Xwayland 1651
2 kwin_wayl 1549

具体占用：

❯ lsof -U 2>/dev/null | grep -v -E "Xwayland|systemd|kwin_wayl|dbus|pipewire|wireplumber" | awk '{print $1, $2}' | sort | uniq -c | sort -nr | head -n 10

可以看到在我这里qq吃掉了251个连接数，把上限挤满了，如果退出qq再重新进入就能释放掉。

有没有朋友遇到类似的问题？

大家都发现了，比如

切换到x11环境下试试呢？验证一下是软件Bug？还是在Wayland环境下对x11协议的窗口程序的兼容性问题？

有人已经试过了：

目前比较好的绕过方法是使用Wayland并且不给用Xwayland。这样剪贴板会不能用，但是不影响别的软件。

有大佬发现可能是QQ内部的bug，给出了暂时的解决方案，参考链接：https://aur.archlinux.org/packages/linuxqq#comment-1062481

有没有谁试过假如 patch Xserver 让它以 LRU 方式强行关掉 QQ 创建的旧连接，会不会有什么影响？

原来是QQ的锅，逆天了我最近经常遇到 vibe 的一个软件（也是xwayland用）经常打不开，我还怪 AI，直到看到日志的第一行 log，才找到这个问题。QQ 你过于逆天了啊！
