When I normally program in Go with the gopls language server, Emacs crashes on autocomplete spots. I can't pin down the precise cases when it happens, because it happens spontaneously, but I have learned to type very fast in order not to toggle autocompletion. It must be mentioned that I use `corfu' with `corfu-auto-delay' set to 0.5 seconds. I enabled traces, and inspecting the trace it shows consistently that the last or so message from the language server is a very long one. Initially, I filed an issue at gopls: https://github.com/golang/go/issues/69368 . However, now it also crashes on autocomplete with Sly! I doubted it is something with emacs initially, thinking the gopls process was somehow crashing emacs. Now, however, I am pretty sure it is something with emacs.   I use Arch linux, emacs version 29.4-2, installed with the emacs-wayland package (with native compilation and PGTK enabled). My computer's specs: CPU: Ryzen 5 4500 GPU: AMD ATI Radeon RX 6400/6500 XT/65 16GB of RAM   Running emacs on wayland with GNOME.   If I can provide better information, please tell me what to do.   In
