70139 - Every window filled with broken window image after a long usage.

Status: RESOLVED WORKSFORME

(Core :: XUL, defect, P3)

Description

[hirata masakazu]

2001022304 trunk for MacOS.
It started in this or around 0221 build.
After a long surfing with a lot of open windows, a window fails to load an image
within a page (JS coded?) and then, the background of the window leaks to the
entire window and every window is filled with the image of this window content.
It is a little bit like bug 55622 and bug 55982.

[Mike Pinkerton (not reading bugmail)]

hrm, sfraser is the de-facto owner of this kind of stuff in general, pushing to 
him for better triage.

How did you determine that memory had run out? Was the heap full? Or was there no 
temp mem left?

Comment 5

[hirata masakazu]

True, I did not really check the memory amount. I usually see that the memory
usage for both finder(system) and Mozilla go up and then weird things start to
happen. 
Removing reference to the memory from Summary.
I will check it when it happens again. So far, I have experienced this only
twice in the same build. BTW, the bug is not corrected by closing the windows.
Relaunching is necessary.

Indeed, the memory did not run out before this bug hit for the third time.
Mozilla crashed after I took a screen shot, probably during check mail. Memory
was a plenty as recorded by Macsbug:
System heap high free space + TempMem low free space = #49105632 (#46M)

Yet of course it is probable that the memory space was fragmented and free
memory for Mozilla ran out in the above example. I had various apps. launched
and used during the time.

This one really looks similar to bug 55622 and bug 55982.
Once you close all the windows and open a new one, the new window is still the
same garbage. At this point, the bar in showing the memory usage in "About this
Computer" window is filled to the right edge.
Then you reduce the window size and then the window returns to normal.
Then the memory usage indicator also shows some unused space in "About this
Computer" window.

This sounds like double-buffering gets whacked to me. -> dcone.

Comment 13

[dcone (gone)]

Is this from the new Image library.

Comment 14

[John Morrison]

This bug report is from Feb 25, so, no, this is not fallout from the new imglib

Comment 15

[Mike Pinkerton (not reading bugmail)]

not libpr0n, back to dcone.

Comment 16

[Asa Dotzler [:asa]]

Comment 17

[hirata masakazu]

Have not seen this for a while.
I guess I can mark this WFM.
