New system, new install of Thunderbird. I get the following error :

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt [GFX1-]: glxtest: DRM render node not clearly detectable. Falling back to using the only one that was found.

Thunderbird seems to work okay, but this is annoying.

Perhaps ask whomever it is that is building Thunderbird for the Raspberry Pi OS. To put it bluntly, Thunderbird is not released or tested on ARM processors.

I would guess, and it is s guess, is that the graphics driver does not fully support the rendering Thunderbird is doing using GFX. You could try disabling Hardware acceleration in settings as that falls back to more ancient rendering options that are less compatibility prone. One thing I think you need to consider is Thunderbird is not actually supported on Raspberry Pi OS.
