Issue 3543: Checkbox are not displayed
http://code.google.com/p/chromium/issues/detail?id=3543
Comment #6 by AndreiJuan:
This issue is *not* permanent, so it's hard to reproduce. I've seen it
affecting
checkboxes, radio buttons and some tiny IMG elements. After each OS
reboot, for a
while Chrome behaves just fine in this respect. I didn't figure out what
triggers it
yet, but at some point Chrome starts to no longer display some of these
elements any
more. I've seen it affecting (among other pages) the checkboxes on Gmail,
radio
buttons on the Netflix plan selection page, and the "+" that expands a
transaction on
the "recent activity" page of the American Express website. It doesn't
always affect
all sites at the same time. Here's how it behaved on the American Express
website a
bit earlier.
The attached file "ChromeIssue3543-NormalPageView.png" shows the normal
view of the
page; the circled "[+]" elements are small IMGs that when clicked expand
the row to
show transaction details and turn into IMGs looking like "[-]".
The attached file "ChromeIssue3543-BogusPageView.png" shows the bogus page
view with
the inspector on top -- the "[+]" looking IMG is not showing. The DIV in
the TD is
highlighted, yet there's nothing to highlight when I hover the <A> in the
inspector.
Interestingly enough, there were 2 ways to "fix" the behavior, with
different
"persistence" levels in time.
Option 1: I Alt+Tabbed to Firefox, navigated to the same page; the page was
displayed
normally there. Alt+Tab to Chrome, refresh page, the "[+]" magically
reappeared.
This is temporary however: Alt+Tab back to Firefox and close it. Refresh
the page in
Chrome, and the "[+]" IMGs are gone again. (This temporary fix worked for
me using
IE instead of Firefox in the past.)
Option 2 (tried it later): In Chrome, I took the URL of the missing IMG
from the
inspector and navigated to it directly, as shown in the attached file
"ChromeIssue3543-AccessingTheImgDirectly.png". I switched tabs back to the
AmEx
page, and the "[+]" IMGs reappeared there. They stayed there even after
closing
Chrome and restarting it, and even after clearing the cache (just the
cache, not the
browsing history).
At this particular time I can't reproduce the same behavior with the
checkboxes and
radio buttons -- on Gmail, Netflix or on the website initially mentioned in
this bug
report (compareindia.com) everything works fine. The issue with IMG may or
may not
be the same as the one with radios and checkboxes, and actually it may or
may not be
a rendering issue(!) -- after seeing option 2 above, with the IMG it could
as well be
a HTTP issue (and perhaps with radios and checkboxes as well, if Chrome is
sometimes
downloading the look and feel images used to display standard elements like
radios
and checkboxes).
Note that with radios and checkboxes, the elements seem to be there even
when they're
invisible, so if you know where to click they change state or do their
actions. With
the IMGs on AmEx on the other hand, clicking anywhere doesn't trigger the
action of
the <A> (perhaps because it's too small without the image and I couldn't
click it).
This issue disappears -- for a while, usually several days -- after an OS
reboot.
I'm using Chrome 0.3.154.9 on Win XP with SP3 (which I used to not reboot
for weeks
until I started using Chrome, so now I have to reboot it once in every few
days).
The only other software I can think of that could somehow interfere with
Chrome
regarding this behavior is BitDefender Antivirus 2009, which every now and
then
quarantines a file in Chrome's disk cache when I access a page containing
some form
of malware. The missing elements Chrome issue seems to me to happen more
often than
these malware removal events though, so there might not be any relationship
between
them.
