--- Comment #26 from Gianluca Pettinello <gianluca.pettine...@gmail.com> --- Coming back to the topic as I'm hard to give up if I think the goal is reachable. The function: Xcb::Property property(false, id, atoms->kde_net_wm_shadow, XCB_ATOM_CARDINAL, 0, 12); as it is called in function: readX11ShadowProperty is the key to get the shadow properly rendered in pop up menus. As already described in: https://community.kde.org/KWin/Shadow the last four uint32_t contain the padding of the shadow (I deliberately injected a piece of code to manipulate them) The first eight uint32_t contain the id of the pixmaps. Who creates the pixmaps. In which point of the code could I find it? Thanks Gianluca -- You are receiving this mail because: You are watching all bug changes.
