Ecs widget behaves unreliably

[mclate]

In some apps (PyCharm in particular), clicking esc doesn't always behaves as expected. In many times i have to click it several times to make it work (especially annoying when using vim-mode to write code). This doesn't happen when default system touch bar is showing (when using native esc button). It also doesn't happen for all apps but for some.

Let me know if there is any additional information i can provide to make troubleshooting of this issue easier. Thanks.
