Compatibility Report

  • Name of the game with compatibility issues: OK K.O.! Let’s Play Heroes
  • Steam AppID of the game: 680700

System Information

I confirm:

  • [x] that I haven't found an existing compatibility report for this game.
  • [x] that I have checked whether there are updates for my system available.

Symptoms

There are two issues at the same time:

  1. With latest Proton the cutscene now work (apaprently previously it would black screen, inclusing the video below the main screen), unfortunately it has bug where it seems like the color layers of the cutscene are split and rendered slightly offset from each other. I will ass screenshots to illustrate.
  2. There's a input issue with the Dualshock 4. Apaprently if you move left and right with the analog stick you will move left and right, if you move left and right with the d-pad you will move up and down.

Reproduction

Play the game normally for the cutscenes issues, it should be reproducible with just the ones from New Game, you can compare with gameplay videos from YT.

For the input issue with DS4 just create a new game and as soon as the beginning cutscenes are finished (or skipped) you will see the issues in controlling the character.

Issue remains on Proton 9.0 (Beta).

I got a hold of a Steam Deck OLED recently.

I didn't test the controller issue on it (didn't connect a DS4 yet) but the issue with the videos where "the color layers are split and slightly offset" happens on the Steam Deck as well.

Update: the issue with the color layers still happens with the latest stable Proton (9.0-4), however it's gone with the latest Proton-GE (9-27)

This should mean that GE implemented some change related to vídeo rendering that should make its way to standard Proton soon.

I did not check for the issue with PlayStation controllers yet.

MMateusRodCosta 2025-04-30 github

So, Proton 10.0-1 Beta launched today and I tested it.

The issue with the offset color layers in the videos is gone!
So, both Proton GE 9-27 and Proton 10.0-1 are confirmed as fixed.

I still didn't test the controller issue

MMateusRodCosta 2026-03-03 github

As of Proton 10.0-4 both issues are confirmed fixed.
