Is there an ETA for ProjectM add-on availability for LibreELEC (Nexus) 11 Beta2 (Generic build)?
It looks like ProjectM version 20.2.0-Nexus has been available since 16 September 2022 (https://github.com/xbmc/visualiza…ag/20.2.0-Nexus) but when upgrading from LibreELEC 10 to LibreELEC 11 Beta 2, the ProjectM add-on was removed as being incompatible with no replacement currently available. 
Thanks in advance!
The Generic x86_64 image switched to GBM/V4L2 graphics which means we use OpenGLES rendering not OpenGL required for ProjectM. The Generic-Legacy image still uses older X11 and OpenGL approach, and ProjectM should be available there, but then you lose HDR support. The Goom visualiser is OpenGLES compatible and similar to Project M.
chewitt - I installed LibreELEC (Nexus) 11 Beta2 (Generic-legacy build) and ProjectM is unfortunately also unavailable,
Goom: Not certain if you meant ShaderToy (which is available for both the LibreELEC (Nexus) 11 Beta2 Generic and Generic-legacy builds) but Goom is a fairly simplistic visualization that does not currently support the wide variety of user generated visualization presets.
Thankfully, I was able to downgrade back to LibreELEC 10.0.4 (Generic build) without too much trouble in order to get the ProjectM add-on back.

Change to build ProjectM for LE11 Generic-legacy has been added https://github.com/LibreELEC/LibreELEC.tv/pull/7553 expect the addon to be available in the next day or so
Possibly related: Note that after installing LibreELEC (Nexus) 11 Beta2 (Generic-legacy build), the Shadertoy add-on seems to be reliant on libGLESv2.so.2:
error <general>: Unable to load /storage/.kodi/addons/visualization.shadertoy/visualization.shadertoy.so.20.3.0, reason: libGLESv2.so.2: cannot open shared object file: No such file or directory
If you installed add-on's with graphics dependencies under GBM and then swapped to X11 you will need to remove the add-ons, clear the add-on package cache, then reinstall the add-ons; else you will have add-ons with GLES dependencies on a GL platform. The same is true if you go in the other direction.
Greetings chewitt. I've been lurking on this thread and watching the available add-ons for Nexus and projectM is still a no-show. I see your involvement at github, but no activity since late February. Would you please provide a status update?
Thx, jasn
Status Update: Drinking morning coffee and trying to work up some enthusiasm for Intel CPU hardware. I'm struggling..
ProjectM was one of my favorite bits of LibreELEC as well and hope to see this be available again soon.

Sadly not seeing any activity on github since February. Updating ProjectM to GBM/V4L2 must be a total PITA, I expect, and wondering if it will ever catch up to the latest versions of LE?
Some progress for v/next: https://github.com/LibreELEC/LibreELEC.tv/pull/7967
