bios 1.13.1 brought keyboard issues

I'm own xps 9550. After bios update to 1.13.1 i have weird keyboard issues. Some key combinations (shift+`, Ctrl+z, Ctrl+v) stops working accidentially for some period of time. Shift, Ctrl, z, v and ` itself works fine, but pressed modifier (Shift, Ctrl) makes pressing letter keys (z, v, `) invisible.

I have dual boot (linux, windows). The issue concerns both.

Re: bios 1.13.11 brought keyboard issues

Downgrade to 1.10.0 finishes partialy (only some components updates successfuly) and doesn't resolve the issue.

Re: bios 1.13.1 brought keyboard issues

I've made a reserch and figured out, that the problem is with my Tilda and Control_L buttons.

When the button is pressed instead of one event "Key press" it generates a lot of "Key press", "Key release" pairs.

Who can be responsible for such behavior - keyboard controller, bios, processor?
