Description
Hi
After the latest SteamOS update (on Deck), when using Video Wallpaper Reborn (or any Qt-based video wallpaper plugin) in Desktop Mode, the animated wallpaper shows green horizontal stripes.
Cause identified:
The developer of Video Wallpaper Reborn confirmed this is a bug in Qt's hardware texture conversion, fixed in newer Qt versions (6.6+). However, SteamOS still ships with an older Qt version that contains the bug.
Workaround:
Setting the environment variable QT_DISABLE_HW_TEXTURES_CONVERSION=1 fixes the issue.
Request:
Could you please update Qt to a newer version in a future SteamOS update, so this workaround is no longer necessary? Many users are affected.
Thanks for your attention!

Research direction
Start by checking the Qt version shipped in SteamOS and the update or packaging process for that dependency. Compare it with the Qt 6.6+ fix and verify the green stripes are gone in Desktop Mode with Video Wallpaper Reborn without setting QT_DISABLE_HW_TEXTURES_CONVERSION.
