Ubuntu Lunar Lobster升级后Wayland频繁崩溃问题求助

我最近把自己的HP Victus桌面（配置是AMD Ryzen 7 5700G + Radeon RX 6600XT）从Kinetic Kudu升级到了Lunar Lobster，大部分功能都正常甚至有所提升，但唯独Wayland出现了之前从未有过的问题：每天会因为休眠唤醒、锁屏解锁操作崩溃好几次，每次崩溃都会直接回到登录界面，所有会话都得重新开始。

最让人头疼的是，崩溃发生时没有任何错误提示能给我排查方向，Ubuntu也从来没弹出过“检测到系统程序问题”的窗口，我完全不知道该从哪入手调试，或者怎么提交有效的bug报告。

我翻了journalctl的输出，找到了一些看起来相关的日志片段，其中关键的报错是org.gnome.Shell@wayland.service: Main process exited, code=dumped, status=11/SEGV，完整的相关日志如下：

之后我尝试查找核心转储文件，执行了以下命令：

$ cat /proc/sys/kernel/core_pattern

输出结果是：

|/usr/share/apport/apport -p%p -s%s -c%c -d%d -P%P -u%u -g%g -- %E

然后查看/var/crash目录的内容：

$ ls -l /var/crash

输出：

total 51148

-rw-r----- 1 mjf      whoopsie 52366746 Apr 26 16:11 _usr_bin_gnome-shell.1000.crash

-rw-r--r-- 1 mjf      whoopsie        0 Apr 26 16:11 _usr_bin_gnome-shell.1000.upload

-rw------- 1 whoopsie whoopsie       37 Apr 26 16:11 _usr_bin_gnome-shell.1000.uploaded

可以看到系统捕获到了一次gnome-shell的崩溃，但从来没提示我提交报告，而且从这个文件的时间来看，之后至少又发生了2次崩溃，都没有被记录或者提示。

有没有大佬能指点下该怎么进一步排查这个问题，或者怎么正确提交bug报告呢？
