window: set the paned as the drag destination (2.30 KB, patch)

Description Ernestas Kulik 2016-06-13 20:00:58 UTC 
Not sure what exactly causes this, but setting the window itself as the drag destination and setting the GTK_DEST_DEFAULT_HIGHLIGHT flag causes the window to flicker and twitch when dragging from the tree view onto the window.

window: set the paned as the drag destination

Setting the window as the drag destination along with the
GTK_DEST_DEFAULT_HIGHLIGHT flag causes the window to misbehave. This
commit fixes that by setting the paned as the drag destination.

Same issue in evince when dragging an image from a pdf file to outside the evince window.
Comment 4 Hussam Al-Tayeb 2016-08-23 11:22:43 UTC 
I tested yelp as well. Dragging an image cases flickering exactly while the image crosses the window border.

This bug is file-roller-specific. You would attract more attention if you reopened your GTK+ one. :)

To expand, this seems to be specifically caused by two things: setting the window as the drag destination and setting the GTK_DEST_DEFAULT_HIGHLIGHT flag.
