Summary

This has been happening a lot lately. I use Whatsapp a lot, but for some reason (I do not have a pattern or action to point to) the page became unresponsible. The only solution when this occurs is close and reopen Tangram.

[sonnyp]

Can you start Tangram from the terminal and see if there is any output when the problem occur?

[tjapro]

It freezed when I was seeing a photo at 17:51. No output when the problem occured ...

flatpak run re.sonny.Tangram

[sonnyp]

Please try to reproduce with GNOME Web / Epiphany flatpak.

If you can - file a bug report on WebkitGTK

There is nothing I can do about this here.

[tjapro]

@sonnyp

Please try to reproduce with GNOME Web

I tried and the problem seems with the Gnome Web and/or Whatsapp itself, but there is a enhancement we can do:

After a while, if a webpage do not respond, the Gnome Web shows a pop-up/small window:

This window/pop-up do not appear in Tangram. If it appears we could reload the webpage (or tab, in Tangram case), without closing and re-opening the Tangram itself.

[tjapro]

Sorry, @sonnyp to add another comment here, but it seems I cannot debug your app for a similar problem (yo can see it at https://bugs.webkit.org/show_bug.cgi?id=249844).

So, I'm trying to debug your app with these commands, but unsuccessfully ...

export GST_DEBUG_FILE="$HOME/gst.log" GST_DEBUG_NO_COLOR=1 WEBKIT_FORCE_SANDBOX=0 G_DEBUG=fatal_criticals

1. flatpak-coredumpctl re.sonny.Tangram
2. sudo flatpak-coredumpctl re.sonny.Tangram
3. flatpak run --devel --command=bash re.sonny.Tangram

What can I do? Or what am I doing wrong?

[sonnyp]

@tjapro you already got the help you need here https://bugs.webkit.org/show_bug.cgi?id=249844#c18

You need the -m parameter

[tjapro]

You need the -m parameter

Thanks for your help, and checking coredumpctl list there isn't any crash from Tangram, because it will not crash ... This is why coredumpctl didn't catch anything.

~Lets see what is the result of the Webkit issue ...~ Webkit team has resolved this issue, but "the change is not in TP yet". We have to wait ...
