Since version 4.4 new color pickter dialog is used as separate window. Immediately there was a problem. When I click on the button to change the color of text or background or anything in Writer, Impress or any other program the new small window with color pickter should appear. But in my computer the window is just beginning to be drawn and immediately disappears. If I click several times (5, 10 or 20) the window may finally appear and I can work with color pickter. It is very uncomfortable. All other dialogs open correctly. The problem there is in all versions more than 4.4.
I use Linux Slackware64 14.0 (glibc-2.15,glib2-2.32.4, …). Locale is ru_RU.KOI8-r.
