System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.12

Blender Version
Broken: version: 2.93.4, branch: master (modified), commit date: 2021-08-31 09:23, hash: b7205031ce

Short description of error
I keep losing texture painting data, literally hours of work, because Blender is very unstable in texture paint mode combined with Eevee and crashes a lot. This would be fine if autosave and manual file saving worked as expected, but neither of these saves modified internal image datablocks, so when Blender crashes, all the work is lost, even if the user saves very frequently.

Exact steps for others to reproduce the error

In a new empty Blend file, switch viewport to Eevee and start texture painting image which is part of at least moderately complex material
Keep saving the file every few strokes to avoid lost work
Blender will eventually crash
Result: The texture paint changes to the image block are lost.
Expected: Blender has an option to save modified image datablocks when the file is saved, so the users do not lose their work.

The question whether to always do the auto-image-saving always (not only on quitting / leaving the file -- which has been added for 2.8) has come up before, see #45636.

So in essence, this is a duplicate of #45636 (Texture paint doesn't prompt user to save painted textures).

All relevant discussion has already taken place there (there is no new information here).
I agree this is still an issue, it should be solved at some point, but devs responsible in this area have classified this as not a bug.
To keep this bugtracker organized, I am afraid I will have to merge this with #45636.
Feel free to raise your concerns in that report again, but there is no point in having two separate task for this.
Note that the API is there, the change would be quite minimal, I think the main question is how to have this implemented:

Would this be a preference?
Would this always spawn a dialog?

But lets please continue discussion in #45636 (think it makes more sense / raises the pressure there)
Thx reporting anyways!
