## Link to GitHub Issue, if one exists n/a ## Description of change `acmFormatSuggest` is known to cause significant perf issues on Linux; add a hook to return cached results. The fix is only active in the Linux variant. For discussion, see * https://codeberg.org/nixac/spicetools/issues/2 * https://codeberg.org/nixac/spicetools/issues/4 ## Testing I've only tested this on Windows, checking if iidx and popn can boot, play songs without audio issues.
