buffers / panels with errors / warnings get mangled such that the gutter displays repeated @ symbols, the source code is hidden, and line numbers are not available. see https://github.com/rust-lang/rust-analyzer/issues/15726 for a screenshot.
seems to only happen when the split is sized to a specific column width (exactly the source code's line length?) - anything above or below does not trigger the issue. likewise, if i address the warning or ignore it via #[allow(dead_code)], the issue goes away.
Reproducing the bug
launch MacVim
open a rust file via :edit path/to/file.rs
split the panel with :vsplit
open a different rust file which has warnings / errors - e.g. "unused method" via: :edit path/to/file-with-warnings.rs
adjust the split until you are able to see the line numbers be replaced w/ @ symbols (given my screen layout, this happens immediately after i launch the split)
