System information

Godot v4.3.beta (92c8e87) - Fedora Linux 40 (KDE Plasma) - X11 - GLES3 (Compatibility) - NVIDIA GeForce RTX 4090 (nvidia; 555.58.02) - 13th Gen Intel(R) Core(TM) i9-13900K (32 Threads)

Issue description

Every time you bake lightmaps with the Scene or Custom Sky environment node in Compatibility, you get this error:

 drivers/gles3/storage/texture_storage.cpp:717 - Condition "t->is_render_target" is true.

Baking still succeeds and the texture is saved to disk correctly.

This error does not occur when baking using Forward+ or Mobile, or when using another environment mode in LightmapGI.

Steps to reproduce

• Bake lightmaps with environment mode set to Scene (the default).
