[Bug 1245040] [NEW] taking chromium-browser full-screen and then not doesn't repaint non-chromium-browser part of screen

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Making chromium-browser display full-screen (by hitting F11) and then
not (by hitting F11 again) does not repaint the part of the screen that
is no longer occupied by chromium-browser.  The following events do
cause the non-chromium-browser part of the screen to repaint, as long as
they occur on the same screen as chromium-browser:

- click outside of chromium-browser
- cause a window other than chromium-browser to take focus (by mousing over it or clicking it -- I use focus follows mouse)

In my dual-head setup, focusing a window on a different screen does not
cause a repaint.

If the mouse is over a pixel in which a non-chromium-browser window will
draw when F11 cancels full-screen mode, then the repaint happens
correctly.

This does not appear to happen in all applications.  For example, gnome-
terminal also interprets F11 as full-screen, but this repaint problem
doesn't occur with gnome-terminal.  (On the other hand, in the case of
gnome-terminal, if the mouse is over a chromium-browser pixel when F11
cancels full-screen, then gnome-terminal returns to normal size, then
seems to receive a maximize event.)

I am reporting all of the above in terms of compiz / unity, because I
suspect the bug(s) do not lie with apps that go full-screen but rather
have something to do with window manager / display manager events.

Title:
  taking chromium-browser full-screen and then not doesn't repaint non-
  chromium-browser part of screen

Status in “unity” package in Ubuntu:
  New

Bug description:
  Making chromium-browser display full-screen (by hitting F11) and then
  not (by hitting F11 again) does not repaint the part of the screen
  that is no longer occupied by chromium-browser.  The following events
  do cause the non-chromium-browser part of the screen to repaint, as

  - click outside of chromium-browser
  - cause a window other than chromium-browser to take focus (by mousing over it or clicking it -- I use focus follows mouse)

  If the mouse is over a pixel in which a non-chromium-browser window
