Audio crackles/gets distorted when resuming play after having Steam Deck in sleep mode with the game running
Sometimes launches in a stretched video mode rather than letterboxing the image as it's supposed to. Changing video options to fullscreen fixes the issue.
Steam release works fine on Steam Deck under normal operation, other than the audio crackling after sleep and the stretched resolution issue. Streched resolution can be fixed simply, but the audio bug needs a game restart (as far as I could tell), which could be annoying if you set the Deck to sleep right before an extended cutscene or boss fight.

Only during Kingdom Hearts 0.2 Birth by Sleep - A Fragmentary Passage, during certain effect heavy attacks or sequences but it's momentary and soon returns to a stable fps
The main point is that this game collection depends on cutscenes and without the lauch options it will not show any pre rendered cutscenes

On Heroic settings change alternative exe to the path of the game you want to launch, for example /home/deck/Games/Heroic/KH_2.8/KINGDOM HEARTS Dream Drop Distance.exe
Cutscenes do work this time but play somewhat slower
You cannot launch the games directly, you need to change alternative exe

Crashes after choosing new game.
I can install and open the menu, but everygame, KH I/II/III ALL CRASH.

the game window seems to minimize, resize, and re-fullscreen (borderless or not) when selecting one of the games available in the collection.
Having tested all the games within this collection and the two others recently released on steam (2.8 and III) it seems that all the games not running on unreal 4 (so prior to 0.2) do not play cutscenes. I will be able to hear audio, and sometimes see subtitles, but there's no image. X backstory doesn't work at all.
This is consistent across all the kingdom hearts titles that were recently released on steam.

Even without the launch options perfectly playable, but you'll need them for playing the intro- / and probably the ending- (pre-rendered) cutscenes.

FMVs dont show without launch option

Use GE-Proton9-7 for the best experience.

Required gamescope to get around black screen issue when switching to games from main selection menu on i3wm.
Steam Deck env var needed for cutscene workaround. Gamescope needed if using a twm like i3wm.
