Created attachment 27939 [details] square_exa_problem.jpeg All this happend sometimes (without using EXAPixmaps): Screen rewriting random part of screen with squares (random data). Fonts are changed to unreadable. Text change color to different color or it turn invisible. Whole window of "Konsole" disappear (min/maximalization didn't help, sometimes help ALT + mouse click, which change windows transparency - that back window to visible state. P.S. Looks like this issues mostly depend on work with EXA and advanced using it by Oxygen or Bespin theme (KDE 4.3). With other themes, problems are rare. With Oxygen more visible, and with Bespin, which using lot of fades, effects etc. are most visible.
look like exapixmaps, which now working perfectly, solved this problem. So, closing as works for me.
