- 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.
