In dual display setup the dialog (xdg-desktop-portal) always pops up on a wrong screen/display if run from non-qt apps (e.g. google-crhome). It doesn't appear on a display where the original application that triggers `xdg-desktop-portal` is run.
Thank you for the bug report! However Plasma 6.1.5 is no longer eligible for support or maintenance from KDE; supported versions are 5.27. (LTS), and 6.2 (non-LTS) or newer. Please upgrade to a supported version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need support for Plasma 6.1.5, please contact your distribution, who bears the responsibility of providing support for older releases that are no longer supported by KDE. If you can reproduce the issue after upgrading to a supported version, feel free to re-open this bug report.
You are talking about the file dialog, right? I haven't tested it, but I would guess this happens when the application doesn't pass a parent window to the portal, so the portal has no idea where the dialog should go
(In reply to Nicolas Fella from comment #2) > You are talking about the file dialog, right? Correct. It worked properly in 23.10 It's frustrating to see so many bugs being constantly brought by every KDE update.
