Can you get the xprop output for the window? --- xcb_size_hints_t hints; xcb_icccm_size_hints_set_min_size(&hints, width, height); xcb_icccm_size_hints_set_max_size(&hints, width, width); I think that this code misses a line to zero initialize `hints`. However, garbage size hints should not crash kwin. -- You are receiving this mail because: You are watching all bug changes.
