196278 - Xlib not redrawing/repainting until input activity

Status: RESOLVED WONTFIX

(Core :: Web Painting, defect)

Description

[Keith]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3a) Gecko/20021212
Build Identifier: 

If a document is graphically changed through a DOM call after it has been
loaded, the xlib event loop does not process the redraw to show the effects of
the change until input activity (i.e. mouse hover) happens on the window it
monitors.

This bug has been verified by Ginsburn.

Reproducible: Always

Steps to Reproduce:
Load any webpage that uses the DOM to graphically change an element after the
webpage is completely loaded.

Example: Set the innerHTML of a <div> to reflect the current time every second.
Actual Results:  
The redraw/repaint is not performed until the window gets input/mouse activity.

Expected Results:  
Redraw should take place immediately after DOM modification.

I remember that I fixed that bug - but it seems the nsITimer changes made a
while ago foobar'ed the fix... ;-(

Can you provide a small testcase, please ?

The User-Agent listed in the original bug report should be ignored. It does not
pertain to this bug. Also, Ginsburn = Gisburn.

Here is a testcase:
http://www.ocsoft.net/mozbug196278.htm

On a build experiencing the bug, you will only see the time updated when the
window gets mouse activity. It should be updating every second. You must be
using an xlib-only build of Mozilla to see the bug.

Attachment: testcase similar to the one described in comment #5

The link in comment #5 seems to be broken. I could reproduce this bug with a
recent xlib firefox build on FreeBSD 5.3. You can also press a key instead of
moving the mouse in order to refresh the window.
