SUMMARY When two windows are open, each starts its own LSP server. This results in a waste of resources and duplicated work. RAM usage is especially bad since for large code bases, clang-format easily reaches 1GB per instance. STEPS TO REPRODUCE 1. Open a file type with LSP support (and, obviously, the LSP plugin enabled). I use clang-format with C++. 2. Open a new window (View > New window) 3. Open your task manager and count the number of LSP server instances OBSERVED RESULT There are as many LSP servers as there are windows open. EXPECTED RESULT A single LSP server is spawned. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.24.0 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2
Interesting. This is strange, I would have assumed that is plugin global.
