Debug Log

Hello!

When I try to upload some media via Whastapp Web, the program uses too much memory until the computer stays without memory at all!

With uploading images, this do not occur with so much memory pressure.
With videos, I need to open Whatsapp Web in Google Chrome (I tested with 4GB normal memory and 4GB zram memory - I have 8gb of memory).

I tested in Tangram and GNOME Web. This dos not happen in Google Chrome.

Fedora 37
Web 43.0
Tangram 1.4.2

The debug comands that I used:

export GST_DEBUG="3,webkit*:6" GST_DEBUG_FILE="$HOME/gst.log" GST_DEBUG_NO_COLOR=1 WEBKIT_FORCE_SANDBOX=0

flatpak run --filesystem=home re.sonny.Tangram

If there is some other debug method and/or command to use, tell me!
