NVIDIA release 550.90.07 stable and 555.52.04 Beta drivers for Linux

NVIDIA has release two fresh driver updates for Linux this week. There's a new stable driver, and an update to the Beta series.

The first from yesterday is the 550.90.07 stable driver with these changes:

Temporarily disabled the GLX_EXT_buffer_age extension on Xwayland to work around a bug that could cause corruption.
Fixed a bug that could cause corruption when the GLX_EXT_buffer_age extension is used on X.org with PRIME render offloading.
Improved the ability of nvidia-modprobe to detect whether kernel modules are already loaded. This corrects an issue that prevented nvidia-persistenced from setting persistence mode on some systems.
Fixed a bug that could cause additional X screens to claim displays that should have been assigned to a prior X screen based on the given X configuration.
Fixed a bug that could cause the X server to crash when graphics applications requested single-buffered drawables while certain features (such as Vulkan sharpening) are enabled.
Fixed a bug that could lead to a kernel panic, due to a failure to release a spinlock under some conditions.
Fixed a race condition which could lead to crashes when Xid errors occur concurrently on multiple GPUs.
With that being a stable driver, everyone should be fine to use it.

And then there's the new 555.52.04 beta driver for today, which follows on from the exciting 555.42.02 Beta driver that gave us Wayland explicit sync from May. Here's the latest changes:

Fixed a segmentation fault when running multi-threaded NvFBC applications.
Temporarily disabled the GLX_EXT_buffer_age extension on Xwayland to work around a bug that could cause corruption.
Fixed a bug that could cause corruption when the GLX_EXT_buffer_age extension is used on X.org with PRIME render offloading.
