Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect, P3)

Description

[miku84]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:86.0) Gecko/20100101 Firefox/86.0

Steps to reproduce:

Hi
I use MOZ_ENABLE_WAYLAND=1 firefox on plasma5 manjaro. It does not happen for all sites. Problem exists for example:
Tabs open: https://www.nba.com/or https://index.hu/
does not happen on https://forum.manjaro.org/latest or gmail
(maybe pictures causing it)

I have 1 minute configured in energy saving for testing purpose (monitor goes off).
When monitor is off, cpu starts very noisy must be CPU or GPU usage. After click, everything goes quiet.

Actual results:

I tested it min 1 hour, so believe me, it is strange, could not find the root cause.
Tried: different kernel (same), MOZ_ENABLE_WAYLAND=0: no issue, different user: no issue
my profile is new, and nothing is changed.

I noticed this thing in about a month or so, maybe about FF 85-86

Expected results:

System should be idle, not full load.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
