why not allow a file such as env.sh to custom the env？

I need set a env export QT_QPA_PLATFORM=xcb for wayland user

When I test this:

https://github.com/probonopd/linuxdeployqt/wiki/Custom-wrapper-script-instead-of-AppRun

it doesnot work ： execv error: Permission denied

this is my AppRun file

#!/bin/bash
HERE="$(dirname "$(readlink -f "${0}")")"
export QT_QPA_PLATFORM=xcb
cd "${HERE}/usr/bin
exec ./newReader "$@"

• Did you make the AppRun and usr/bin/newReader executable?
• You should not need to cd, just exec "${HERE}"/usr/bin/newReader
• Try using /bin/sh instead of bash

Which system has anything else but QT_QPA_PLATFORM=xcb set?

ubuntu22.04-lts use wayland default，for some reason : https://forum.qt.io/topic/142827/what-can-i-do-for-my-qtwidget-program-s-window-correctly-positioned-on-the-screen/37?_=1689556962349

i have to give a 「xcb」env to my app，

i have a tast as you say, but it doesnot work.

without「xcb」,Qt-App cannot move the window to the right way in wayland

Argh. Wayland breaks so many things...

Can you provide a link to your AppImage so that I can help? Thanks.

Wayland in KDE Plasma 5.27.5，does not need 「xcb」 any more，everything is ok.

while，Wayland in Gnome，need 「xcb」 .
