--- Comment #1 from farsee...@gmail.com --- I forget to kill other irrelevant apps before getting the output. Here is the new output by leaving only plasma and konsole and kwin on screen: `xwininfo -root -tree`: http://cfp.vim-cn.com/cczz `xprop -id 0x2000030`: http://cfp.vim-cn.com/ccz0 `xwininfo -id 0x2000030`: http://cfp.vim-cn.com/ccz0 And another detail, I tried this on 3 of my laptops, with different screen size. 1366x768, 1600x900, 2560x1600 . The black windows all "seems" taking 1/4 of the screen, and there is always a window with 640x480 geometry in the `xwininfo -root -tree` -- You are receiving this mail because: You are watching all bug changes.
