Regarding patch 4/10, should we just forbid creating multisample NPOT textures in the first place? **Sadly I'm sure nobody has a GPU of that era to test with**...
Sorry for jumping-in. Just for the sake of completeness, I think [Stefan Dösinger](https://gitlab.freedesktop.org/mesa/mesa/-/issues/347) has (or had) some access to old RV530 Radeon hardware. :wink: And when it comes to old GPU hardware Mesa driver development, [Pavel Ondračka](https://gitlab.freedesktop.org/ondracka) is also in 2024 quite active in regard to the r300g Radeon driver. :thumbsup:
