I don't think so. The 'Firefox::Screenshots' component works fine, but the displaying of firefox:main is broken or lacking.

So, it seems that the graphic memory has the complete data, but the displaying process of firefox:main doesn't take the memory's data completely.

Means, the Firefox:core:displaying process taking out the graphic memory data incompletely..

There could be some relations with Tabbed browser.. Cause, opening mainwindow with some other child window by add-on:Popup window or from main to make child window to retweet

it happens.

There are two kind of pngs attached, one is taken by the component, the others are taken by app from outside from firefox.

"Screenshot at" s are by app from outside.
"Screenshot 2021 …” is taken by the component.

Hi,

Could you please answer the following questions in order to further investigate this issue?

1- Does this issue happen with a new profile? Here is a link on how to create a new profile: https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles
2- Are you using add-ons? If so could you please list them? (you can try the issue while in Safe Mode. You can find helpful info here : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode .)
3- Does this issue occur in the latest nightly version of firefox? Here is a link from where you can download it: https://www.mozilla.org/en-US/firefox/channel/desktop/

Thanks for the report.

Hi,
I've set the font on firefox from linux mint default:Takao to Noto . and monitoring so far..
https://bugzilla.mozilla.org/show_bug.cgi?id=1722426#c12
The trouble looks calming ..
It seems being known that the Takao font sometimes makes garbled characters on firefox...
It might be this kind of thing...
Thanks.

The following report is just after the crash.
https://crash-stats.mozilla.org/report/index/ec4b6b9b-46bc-4211-86d0-a42da0210831

Just before above happening, garbled characters had happen,

and linux mint mate-screenshot --interactive captures only garbled charactered display,

but firefox component "Firefox Screenshots" takes picture as the characters as it should be...

The crash report in comment 14 shows "assertion failed: self.font_contexts.lock_shared_context().has_font(&font.font_key)", which sounds like webrender failed to receive or register an expected font resource. We've seen a few reports that seem quite similar, IIRC; Lee may remember more about these.

I'm not sure now, at what time I've changed the font settings from default(Takaos) to Droids and monospace...

Might be after got crash on the settings of "webrender: false", and "font default(Takaos)"...

Now, the font settings for Japanese etc. are Droids and monospace , checking "Allow ...", and "webrender, false".

The terminal console, until crash. Just before crash, I clicked some add-on icons and they showed a blank menu pop-up each time... and soon later, crashed.

firefox nighly launched from terminal and typing firefox-trunk,
can't find about:crashes and bug-reporter seems doesn't work...

How much RAM do you have installed, and how much is available for applications to use? The information from something like "top" would be helpful here...

This is a report from Nightly, but there is no Snap Nightly, that's why I removed this bug from the snap meta bug.

(Jonathan Kew (:jfkthame) from bug 1737810 comment 41)

That looks like it may actually be an OOM (see the GraphicsCriticalError annotation).

I wonder if this is actually FreeType encountering an OOM situation (maybe remaining memory is too fragmented for the big font file) while trying to read the font, but returning Unknown_File_Format rather than Out_Of_Memory? I see a similar "wr_renderer_render: OutOfMemory" annotation in some of the other reports, too, though by no means all of them.

bug 1729779 is in see See Also.

Whether is it related with https://bugzilla.mozilla.org/show_bug.cgi?id=1737810#c53 or not,

I've changed about:config, dom.storage.snapshot_reusing "false" to "true"

So far, no crashes, only two times at the risk though...

Can you try setting the pref gfx.webrender.multithreading to false? That might use less font threads and as such less memory loading the font into each thread, hopefully forestalling any OOMing.

(In reply to Lee Salzman [:lsalzman] from comment #51)

"setting the pref gfx.webrender.multithreading to false" seems to lessen crashes, but not completely.
