我刚刚将桌面更新为 Bookworm。现在每次我启动游戏时，颜色都会乱七八糟，屏幕显示如下：
即使关闭游戏后仍然如此。唯一的解决方案是关闭并重新打开会话。
重现这种情况的唯一用例是游戏，因为它们通常使用特定的显示模式。打开 GTK 或 Qt 窗口时不会发生这种情况。仅适用于固定分辨率或全屏的游戏窗口（例如：wesnoth、SuperTux 2、Mednaffe 中的模拟游戏）。这种显示方式怎么称呼呢？
这是显卡：
Advanced Micro Devices, Inc. [AMD/ATI] Oland PRO [Radeon R7 240/340 / Radeon 520]
我确实安装了以下软件包：
firmware-amd-graphics
xserver-xorg-video-all
libdrm-radeon1
无法在此处发布完整的 Xorg 日志文件。这是似乎相关的部分：

看起来 radeon 驱动程序在某个时候出现故障，系统会退回到默认驱动程序。
这是正确的吗？我可以做什么来解决这个问题？
.xsession-errors当syslog图形混乱实际发生时，我没有看到更多的东西。
