Digging a bit more in TextRenderer shows that the problem comes from the fact that TextRenderer build a cache of the strings that were previously rendered in textures. The textures were most probably deleted after the call to GLEventListener.dispose().

It is not possible to add a cache invalidation method to the TextRenderer by overriding because the stringLocations is private.

It is however possible to avoid building cache by creating a new TextRenderer for each string to draw, as shown here.

Sad, but performance remains OK for me with small charts.

I dropped a ticket here to think about adding this cache invalidation method.
