Description

  • VSCode Version: 1.11.2 (Commit 6eaebe3b9c70406d67c97779468c324a7a95db0e)
  • OS Version: Ubuntu 16.04.2 / Windows 10

Steps to Reproduce:

  1. install/start X server on Windows system (Xming, MobaXterm or VcXsrv)
  2. start code on Linux box (make sure your SSH client has X11 forwarding enbled), use AltGr to compose "{" or similar, cursor jumps left. Interesting to note that both the "{" character and the cursor-left move are produced. This has started with VScode 1.11. Same with code-insiders. Don't get me started.
  3. Tested on 4 different computers.

Contributor guide

Research direction
Investigate how VSCode processes AltGr key events via X11 forwarding. Focus on the Electron layer and key mapping to understand why AltGr triggers cursor left movement.
