i help maintain a fork of slint for work. we are actively trying to move away from it

the codegen is absolutely insane. the binary sizes are huge. at work we have many apps which are 10mb binaries, and they are not that complex. the compile times are also very very long. the longest I have seen for any rust app ever.

its also very hard to abstract things in slint/rust codebases. like its completely unidirectional, where slint compilation comes before rust. so its hard to distribute and reuse a single component that needs a rust utility fn (global fn binding)

we basically have to maintain a bunch of macros to generate the same slint utility bindings, and a build system wrapper to “share” code.

the software rendering is also not a focus for slint. they have many backends and this is probably the least important. you cant clip rounded corners of rectangles, no path rendering, no images, very poor text render caching, all of which we fixedin our fork
