My 2016 MacBook Pro's Touch Bar is acting weird since this weekend.

Sometimes, it will show up garbled up like the picture below, sometimes it will work normally.
In all situations, the tactile features work properly, including Touch ID and power button. It's only the display that is unusable.
Also, a screenshot of the Touch Bar leads to a normal result.

Any one has ever experienced this? I don't want to put more than 50$ into this computer. It's already gotten two new logic boards and a new display over the past three years (totalling more than 1600$, because the first replacement was on warranty).
The Apple stores are out of question, because I need the computer starting next Tuesday until December, and my local one is closed until further notice.

I had mine do this the other day and become unresponsive. Open your terminal, and copy paste the following:

pkill "Touch Bar agent";
killall "ControlStrip";

You may need to sudo it first. If it still happens or comes back, there's a deeper issue at play and I would suggest heading back to Apple.
