NVIDIA 550.54.14 driver released as stable

NVIDIA today launched the 550.54.14 Linux driver as stable coming with a whole bunch of fixes and improvements, so here's all that's changed.

Seems NVIDIA took on what I said to them about their recent changelogs being confusing for end-users (noted in the previous NVIDIA Beta article), so now they're including a note on changes between this version and the last in the same series. 

So the changes from the previous 550.40.07 Beta to this stable version are:

• Fixed a bug that caused HDMI FRL displays to flicker or blank when enabling VRR with 8 bits per color channel.
• Fixed a regression introduced with the 550.40.07 beta driver which caused corrupted window decorations in some applications when running on GNOME.
• Fixed a bug where vkAcquireNextImageKHR() was not returning VK_ERROR_OUT_OF_DATE_KHR when it should with WSI X11 swapchains.
• Fixed a bug where fences passed to VkSwapchainPresentFenceInfoEXT could signal earlier than expected when a WSI X11 swap chain becomes out of date.
• Fixed Xid errors on Hogwarts Legacy and Forza Horizon 4.
• Added support for the VK_KHR_video_encode_queue, VK_KHR_video_encode_h264, VK_KHR_video_encode_h265 and VK_KHR_video_maintenance1 extensions.
• Fixed a regression which prevented some Vulkan applications from receiving VK_DEVICE_LOST upon a VT switch, which could lead to the application hanging or behaving incorrectly.
• Fixed a bug that prevented nvidia-installer from honoring the --gbm-backend-dir command line option.

Meanwhile the changes on top of that when going from the 545.29.06 driver to this version are:

• Fixed an issue that sometimes caused Wayland applications to run at less than one frame per second on Maxwell, Volta, and Pascal series GPUs.
• Fixed a bug that caused an intermittent drop in desktop framerate.
• Fixed a bug that caused “Flip event timeout” messages to be printed to the system log when displays are hotplugged when nvidia-drm is loaded with the fbdev=1 kernel module parameter.
• Fixed intermittent Xid errors on Horizon Zero Dawn, Metro Exodus, Forza Horizon 5, and Halo Infinite.
• Fixed a bug which prevented the “NoMaxPClkCheck” mode validation token from working on single-link TMDS (e.g. DVI, HDMI) outputs.
• Fixed a bug that allowed VRR displays to be driven below their minimum refresh rate, resulting in a blank or flickering image.
• Added an application profile to improve Kwin performance on hybrid GPU systems by setting OGL_DEDICATED_HW_STATE_PER_CONTEXT=ENABLE_ROBUST.
• Updated the build process for NVIDIA kernel modules to honor the INSTALL_MOD_DIR Kbuild environment variable.
• Added support for R8, GR88 and YCbCr GBM formats.
• Optimized the X driver headless framerate limiter to more closely mimic upstream behavior and prevent it from activating in inconvenient situations. Added a new X config option LimitFrameRateWhenHeadless to disable the headless framerate limiter.
• Fixed a bug that prevented Gamescope from running when using the NVIDIA Open GPU Kernel modules.
• Fixed a bug that prevented the installer package from being unpacked on systems where zstd is not installed, when /tmp is mounted noexec.
• Use transparent huge pages when available for the .text section. This is done through madvise() calls, and requires CONFIG_READ_ONLY_THP_FOR_FS.
• Changed the name visible in /proc/devices of NVIDIA devices and the NVIDIA control device from “nvidia-frontend” to “nvidia” and “nvidiactl”. Scripts which parse /proc/devices (such as udev rules) may need to be updated. Note that the conventional /dev device paths like /dev/nvidia0 and /dev/nvidiactl remain unchanged.
• Fixed a bug that could cause some multi-GPU systems to crash on suspend.
• Fixed a bug that could cause the system to crash when an application is run with __NV_PRIME_RENDER_OFFLOAD=1.
• Fixed a bug which prevented application profiles from getting applied to PRIME Render Offloaded applications running via Wine.
• Disabled PRIME Display Offload Sink support for virtual displays on datacenter GPUs. This prevents unusable desktop layouts from getting automatically configured on systems with a mix of physical and virtual displays.
• Fixed a bug that caused high CPU usage during system suspend, which could lead to the system not entering s2idle in some cases.
• Fixed a bug that caused the nvidia-settings control panel to crash when running on Wayland with newer versions of libwayland-client.

There's more listed on the official changelog, but a bunch of those were available in older NVIDIA driver releases, as NVIDIA list all changes since the previous Production release.
