Switching from egui to Slint shrinks Rust GUI binary 4.5×
By replacing the GPU‑dependent egui (which pulls in wgpu) with the CPU‑rendered Slint library, the author reduced the rproc system monitor's Rust binary from ~135 MB to ~30 MB—a 4.5× size drop. The rewrite highlights how heavyweight GUI dependencies can bloat memory even when the core logic is lightweight.
