Seems like scene `RenderData` only gets synched once from `Scene` to `BaseRender` in `RE_InitState` . Animation on it is only evaluating on the scene, so the the `BaseRender` `RenderData` is not properly updated here. However `R_STAMP_DRAW` is part of that and it is the `BaseRender` `RenderData` that is checked in `do_render_full_pipeline` (not the `Scene` one) to determine if we want to stamp. Later calls to `BKE_render_result_stamp_info` / `renderresult_stampinfo` / `stampdata` always get passed the scene, so individual animation stamp details (such as Render Time) work properly. So to resolve, use the `Scene` `RenderData` (rather than the `BaseRender` one) for proper animation update. NOTE: this (not updating animation of members of `RenderData`) might actually be a problem elsewhere, too -- havent checked on this in detail though Pull Request: https://projects.blender.org/blender/blender/pulls/120429
