So that's not it. And my list of open buffers does go up or down a bit, but as I'm working on TS stuff, it's mostly the same handful of smallish files. Note that I used the third-party tree-sitter implementation for a long time and never encountered this. And it never seems to happen if I leave the explorer/inspect mode off. Note that I do do a lot of repeat editing in the ones that have those modes active. There's definitely something going on here, and I wish I had more information to give you, Yuan! > Yuan
