(solved in Digikam upstream) Hyprland (git version and 0.50.0) freeze when trying to drag and drop/copy files/images inside Digikam when using confirmation/choice dialog box

[maderios]

Conditions:
Arch Linux
Hyprland 0.50.0 or/and git versions
qt6 6.9.0-2
qt6-wayland 6.9.0-2
This bug is not present when using Sway, that's why i report here
Digikam git freezes (exactly when i click on 'copy here/move here' when mouse is over destination album) when I try to move files from album. It freezes whole desktop as soon as popup appears over destination album, so i can't click. Desktop is back after killing Digikam window with keyboard shortcut.

Same issue with Hyprland git version commit b5c0d0b (compiled on Arch)

Can you "restore" the desktop by hitting escape?

[maderios]

Yes, i discovered later I can restore desktop using escape key. More precisions: inside Digikam, , i can't drag and drop images from album to another one with mouse but i can do it with right click function "move to album". I can't move album/folder to another one with mouse: "move here" "copy here" "cancel" are frozen, like for images.

likely the dnd op fails to "finish" somehow. xwayland dnd is very wonky.

[maderios]

It seems problem doesn't come from xwayland
I get same issue after building Hyprland without xwayland
In my Arch PKGBUILD
-D NO_XWAYLAND:STRING=true

This bug concerns only Hyprland, it's not present when using other wayland WM like Sway, Niri or/and Labwc

[maderios]

I discover freeze issue happens when using confirmation/choice box (no way to disable it now) that appears when I want to drag & drop files inside Digikam window. There is no DND problem when i drag and drop files from Digikam window to "Digikam batch queue manager" which is separate window beside Digikam window. This "Batch queue manager" doesn't ask me any confirmation/choice, that's why it works fine with Hyprland I think.

[maderios]

New observation: I can silently drag/copy/drop a file with CTRL+LEFT click (but not move) successfully inside Digikam. No confirmation is asked. This confirms that Hyprland issue is related to specific Digikam dialog/choice/confirmation box. This bug is not present with similar dialog box in pcmanfm-qt.

It was a Digikam issue . It's solved now
