Yeah, I've run into this issue with Flatpak & Kate. (I think it was specifically the Flathub Kate Flatpak that was pulled?) FWIW I was recently able to get a "passable" but not ideal Rust/LSP/Rust-Analyzer/Cargo setup mostly functional via use of the kate build plugin and e.g `flatpak-spawn --host cargo build`... ...and... `flatpak-spawn --host cargo run | sed --unbuffered 's/\x1b\[[0-9;]*m//g'`. Excuse the cough. :D (It was necessary to remove the ANSI colour codes produced by some logging library the project used.) (My preference would be to use AppImage but unfortunately recent Kate AppImage versions have a hang-on exit bug.)
