KolourPaint is very close to an exact clone of MS Paint from around Windows XP.

There are also xpaint and Pinta, which are somewhat different, but might satisfy your requirements too.

I use kolour paint on kde, there are a lot of other similar FOSS softwares around too.

I just ran MS Paint (XP version) using wine. You just need to install mfc42 library and it runs great.

Linux Mint has a program simply called "Drawing" that does exactly that. You can resize pictures, draw shapes, write text, paint and save as other formats. It's a big buggy and unoptimized, but it's cool. For simple things, it's sometimes more convenient than GIMP.

No, I need to improve wine's lack of direct 2D and uianimation implementations 😁 there's about 100 or so unimplemented functions calling my name.

Psst. I got really good progress over the weekend.

I got this working by modifying and compiling Wine from source. My approach was to read the crash logs and apply fixes to the missing DLL implementations as they popped up. Most of the required functions already exist in Wine, they just return "not implemented" errors.

The two main issues:

1. Installation crashes - caused by incomplete code in a window animation DLL. This should be relatively straightforward to fix properly.
2. Runtime crashes - caused by missing Direct2D implementations. These are more complex to implement.

What you see in my screenshot is a proof of concept. It loads successfully and basic interaction works, though it's not fully functional yet. I'm planning to release my custom Wine branch this weekend so others can help.
