IDE recurringly pops up when I run Arduino: examples

[mbardwell]

Issue Type: Bug
Extension Name: vscode-arduino
Extension Version: 0.2.26
Arduino Version: 2:0.1.5+dfsg2-4.1
OS Version: Linux x64 Ubuntu 19.04
VSCode version: 1.35.1

Output says:

The Arduino IDE windows stop popping up after I close vscode.

What I expect when I click Arduino: examples (source)

[mbardwell]

It was the version (sudo apt install arduino). When I switched to Arduino 1.8.9 it worked fine.
