Bug Report

What's the issue you encountered?

In Just Dance 2018, 2019, 2020, 2021, and 2022, many of the song videos are not displayed correctly. This manifests as visual glitches, of varying severity, similar to video compression artifacts. See the below screenshots for examples.

How can the issue be reproduced?

Start up any of the affected games in the series, and choose one of these songs. Other songs may have this bug as well, but these are known examples:

• Just Dance 2018: "Rockabye" or "Footloose"
• Just Dance 2019: "Bum Bum Tam Tam" or "Work Work"
• Just Dance 2020: "Rain Over Me" or "Con Calma"
• Just Dance 2021: "Yameen Yasar" or "Zenit" The issue is most noticeable during actual gameplay, but can also be seen in the song's preview video (in Just Dance 2019 and later).

Can someone also check if the demos for these games were also affected?, that way it’ll be easier for users without the main game to be able to track it down.

Might be worth to retest this one due to the recent NVDEC fixes.

I tested this today, and the issue is still present as of version 1.0.7066.
