Blinking and unresponsive window on start. GLSL 4.50 is not supported.

[LeonMarchetti]

• VS Code Version: 1.55.2
• OS Version: Linux 5.11.16-arch1-1 x86_64

When I open Visual Studio Code as I did normally the window opens unresponsive, blinking between gray and black after a few seconds, and showing the last opened file name and directory name in the title bar.

Was working normally yesterday. The OS I use is Arch Linux with packages up-to-date. Installed some new system packages, including wine, but couldn't solve my problems after uninstalling them.

Didn't install any new extension since last working time.

Steps to Reproduce:

1. Open Visual Studio Code, from desktop manager or terminal.

Does this issue occur when all extensions are disabled?: Yes

Attached file code-verbose.txt shows output of running code --verbose.
code-verbose.txt

An error I see in the verbose output is: GLSL 4.50 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.40, 1.50, 3.30, 4.00, 4.10, 4.20, 1.00 ES, and 3.00 ES

Just opened Code today (after shutting down and powering on) and now it works normally. Yesterday I even tried restarting but didn't solve it. I still have no idea where the problem with GLSL came from.
