Simulink编译模型后KDE Plasma 5 GUI严重卡顿且需重启的问题求助

每次我在Simulink里编译模型时，KDE Plasma相关的GUI元素就会开始严重卡顿，直接导致电脑完全无法使用。这种卡顿会一直持续，直到我重启系统——因为卡到连注销界面都没法访问，我甚至专门写了个bash脚本从终端触发重启。这个问题已经折磨我好几个月了！

我已经尝试过以下操作，但卡顿问题依然存在：

• 彻底重装系统到Ubuntu 22.04 LTS
• 安装了HWE（硬件启用堆栈）
• 更新到最新的6.5.0内核

同时我也做了一系列系统监控排查，却没发现任何异常：

• 实时监控硬件温度
• 用ps aux、top（按CPU使用率排序）查看进程状态
• 用free -h检查内存使用情况
• 用nvidia-smi监控GPU空闲内存

实在找不到问题根源，现在已经黔驴技穷了，恳请大家帮忙分析解决！
