Steps to reproduce issue

RViz2 does not start and segfaults immediately at startup on a very fresh install of Ubuntu Noble + Jazzy from today.

My GPU is AMD Radeon RX 6400 but I'm not sure that this is relevant because even LIBGL_ALWAYS_SOFTWARE=1 rviz2 crashes the same way.
I tried other values for OGRE_RTT_MODE as suggested here with no different outcome.
The segfault pops from in GLRenderSystem::initConfigOptions()

Expected behavior

~$ rviz2 opens a new window.

Actual behavior

~$ rviz2 segfaults with the following backtrace:

Core was generated by `rviz2'.
Program terminated with signal SIGSEGV, Segmentation fault.

Additional information

Update: here is what I tried later:

• Start RViz2 from a Docker container that works properly on other machines: same segfault
• Remove the Radeon GPU: RViz2 starts properly!
  I wonder whether this issue should be reported to upstream OGRE instead?

[ymollard]

Just tested with OGRE version 14.6.0 (Tsathoggua), no segfault. The latest available precompiled Ogre in Ubuntu Noble is 1.12 but the bug is there with that version too. I guess I'll have to compile it myself for Jazzy.
