Issue

Drag-and-drop a file from a nemo or caja window to a window in a window-group (such as two firefox instances) does not work, more specifically the window over whiches window-preview is hovered does not come to foreground so one could drop the file into it.

Steps to reproduce

install Linux Mint 21.1 x86_64
open two firefox instances (or, probably, any other program that can have multiple windows under one icon in the taskbar)
open a nemo or caja window
drag a file from the nemo or caja window over the firefox taskbar icon (the window preview showing the two ff windows appears)
the window does not come to foreground, so dropping is not possible / does not cause ff to accept the file

Expected behaviour

hover over taskbar icon (previews appear)
hover over one preview
corresponding ff window comes to foreground and accepts dropped file

Other information

This bug breaks a very central feature of a desktop OS
It used to work perfectly under mint 20.x.
Bug is kind of indeterministic, because sometimes I cannot reproduce it with caja and dragging and dropping between several caja windows does work.

It seems to me, that I have the same issue, but with dragging and dropping any downloaded file in the Google Chrome browser to any program in the taskbar. I'm sorry if I'm wrong. I'm a newbie in Linux. output

Hi,

I can reproduce this with files dragged from nemo to any programme in the taskbar, e. g. evolution. As this seems to be quite a basic functionality of a DE I hope it can be fixed soon.

Hi, I upgraded from linuxmint Una to Vanessa last week, and experienced this regression issue as well.

Click-and-drag an image file from within nemo window, drag file to bottom panel (taskbar) to hover on another open window (group) e.g. firefox for gdrive upload, the second window does not come into focus like previous behavior in una.

Click-and-drag directly from side by side from one to another open windows works.

This is hard as i sometimes work with more than five windows open e.g. nemo, firefox, chromium, gimp, inkscape, evince/xreader, etc. And it's a constant little annoyance in user experience that i have to specifically search and get both nemo and target window open side-by-side before commencing direct click-drag-and-drop to target window without able to use the previous behavior through bottom panel of open windows to focus.

Other than this issue, most other things works very smoothly and I'm satisfied so far.

Hope this issue can be looked into and be fixed soon. Thank you very much.

I can confirm that this issue is still perssitent in 2024 on Linux Mint 21.3, Cinnamon 6.0.4. It never worked on any of my installations, but I have sucessfully used in on my friends' computers with Linux Mint and Cinnamon. It's baffling.
