Status: UNCONFIRMED

(Core :: Graphics: WebRender, defect, P3)

Description

[Adam Drury]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/130.0.0.0 Safari/537.36 Edg/130.0.0.0

Steps to reproduce:

Same as issue #1897006 for version 126

Memory usage creeps higher and higher throughout the day as shown in Windows 11 Task Manager, restarting Firefox will reduce it to start at around 300mb, when it gets to 3GB in use, the browser becomes unresponsive and slow. Reverting back to 115ESR resolved the issues

Actual results:

Memory usage creeps higher and higher throughout the day as shown in Windows 11 Task Manager, restarting Firefox will reduce it to start at around 300mb, when it gets to 3GB in use, the browser becomes unresponsive and slow. Reverting back to 115ESR resolved the issues

Expected results:

Memory clears itself to run a smooth session

The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Can you post a copy of your about:memory after memory usage is high?
