--- Comment #55 from Walter Nicholls <wal...@nic.gen.nz> --- OK that didn't seem to fix it. kwin_x11 process definitely has environment variable set: walter@rukbat:~$ xargs --null --max-args=1 < /proc/`pidof kwin_x11`/environ | grep KWIN KWIN_EXPLICIT_SYNC=0 This occurred with firefox, had about 3 tabs open, then opened two new tabs (with Ctrl-Click on link) - they 'seemed' to be taking a long time. Then I realised why... Then it "infected" the next firefox window, the one I was adding this comment on. So once occurred - can click on each tab in the firefox window and the TITLE BAR changes (eg to "New Tab - Mozilla Firefox" , then "Slashdot: News for nerds ... - Mozilla Firefox" etc) but the client area of the window is not redrawn. That includes scrollbars, the tab bar itself, menu bar (although menus themselves pop down: probably they are new windows). I can right-click on tab and select "Move to New Window" which is what I've just done to type this! Pressing Shift-Alt-F12 twice (to toggle the compositor) repairs the problem and the window starts updating again. -- You are receiving this mail because: You are watching all bug changes.
