My application supports, under Wayland, both ways of taking screenshots, the KWin and XDG Portal. Both seem to be broken at the moment but adding X-KDE-DBUS-Restricted-Interfaces=org.kde.kwin.Screenshot to the xdg-desktop-portal-kde desktop file as Jan suggested,
seems to fix the XDG Portal screenshots at least. </div>

Do I understand correctly that you will fix this so far that we don't need to manually add entries to the xdg-desktop-portal-kde desktop file?</div>

Also, KWin Screenshots, like done by Spectacle, are not going to be available to non KDE Applications anymore? </div>

<div>This patch is to lift the <br>

</div>
<div>For Wayland, I recommend using xdg-desktop-portal standard API to use a portable durable standard API.<br>
</div>
<div>I am fixing its support in <a href="https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/32">
https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/32</a></div>
<div>I thought it had already been done, sorry for this.<br>
</div>
<div><br>
</div>
<div>And if this does not fill your need, well, do the same as <a href="https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/32">
https://invent.kde.org/plasma/xdg-desktop-portal-kde/-/merge_requests/32</a> in your application.</div>
<div><br>
</div>
<div>But this screenshot API is not meant to last very long, as this is not Wayland worthy security-wise.</div>
<div>This would need better standardisation for instance a Wayland Protocol ideally.</div>

<div>Sorry for caughting you unaware.<br>
