Unable to type accented characters in integrated terminal

[mxrsoon]

• VSCode Version: 1.49.0-insider
• OS Version: Linux 5.4.0-42 (Ubuntu 20.04.1)

Steps to Reproduce:

1. Set Brazilian Portuguese as your input language.
2. Open VSCode's integrated terminal.
3. Try typing any accented characters using accent key + letter key combination (~ + a).
4. See that they don't show up in the terminal.

Here I tried typing "título início razão metrô" in VSCode's integrated terminal:

Here I tried the same in gnome-terminal:

Does this issue occur when all extensions are disabled?: Yes, it does.

Additional notes:

• My input method system is set to XIM. I switched to it to be able to bind the Ctrl+Shift+U key combination to an action.
• Pasting accented characters works.

I have the same problem, it started to happen after I switched my keyboard to a USA International

Maybe related to microsoft/live-share#3818.

I managed to fix the bug. I uninstalled vscode through Ubuntu software, then changed the name of the .vscode and .config/Code folders. Then I installed it using the .deb of the site itself, and the accents were working again.
I renamed the names of the folders I had changed again, to return to the old settings, and voiala

Strange, I thought they both were the same version, same package, just distributed through distinct channels.

I will try this workaround later.

I also found it strange, but tried to install it in other ways to check it out.
By the sudo snap install code, it didn't work. Not for apt-get either. I tried to reinstall using Ubuntu Software itself, and it didn't work either, but when I installed it with .deb, it worked...
