New issue 21481 by earthsound: when opening tabs in the background, screens
do not repaint when clicking over to new tabs, with Ctrl+Tab, or even
Alt+Tabbing to a new window
http://code.google.com/p/chromium/issues/detail?id=21481
Chrome Version: 4.0.208.0 (25857)
Other browsers tested:
Safari 4: OK
Firefox 3.x: OK
IE 7: OK
Opera 10: OK
Google Chrome 3.0.195.17: OK
K-Meleon 1.5.3: OK
What steps will reproduce the problem?
Open content in background tabs (e.g., I Ctrl+click on a link) and then
moving to those tabs either by clicking on the
tab or kb shortcut. Once I force a redraw, e.g. by "restoring" the chromium
window from maximized to windowed size, the
current broken screen will repaint properly & once I've done that for that
tab, that tab is no longer broken although
other tabs still may be broken until I force a redraw on those, as well.
What is the expected result?
When I click on a tab that is not currently up front (or Ctrl+Tab to one or
even Alt+Tab to another maximized chromium
window), I expect to see the content of that tab.
What happens instead?
I see the content of whatever was painted on the screen last. This could be
the last tab, it could be menu a menu from
something in the taskbar, etc. Note: the text in the tab & the address bar
of the broken tab correctly shows the title of
the page that *should* be drawn as well as the correct URL.
Please provide any additional information below. Attach a screenshot if
possible.
I only started noticing this when I grabbed the latest build as of last
night (I think I had gone from build 253xx to
258xx).
I first saw issue while Chromium is maximized, but it doesn't have to be in
a maximized window. I've seen this in full
screen, as well, but it isn't 100% reproducible
I've seen this on 32-bit Vista Ultimate SP2 & 32-bit XP Pro.
Screenshots attached.
In repaint_bug_screenshot1.png, notice that I'm currently on the 2nd tab
from the left (should be seeing http://www.mail-
archive.com/chromium-bugs@googlegroups.com/msg30315.html in that tab, as
shown in the tab text and the address bar).
Also, notice the greenshot menu showing in the bottom right. Greenshot is
what I used to take a screenshot of the
chromium window, the menu was not actually open when the screenshot was
taken, this bug just doesn't repaint the screen.
In repaint_bug_screenshot2.png, I've moved numerous windows from other
programs over the area.
