Scrolling and Animations Sluggish

[Grid]

Description of the issue:

• Scrolling the page using Brave is sluggish in comparison to Chrome and Edge.
• It appears that there are random dropped frames. Interestingly, it sometimes scrolls smoothly, but rarely.
• This started around 1-2 months ago.
• I don’t notice any abnormal CPU / RAM spikes.
• Further testing shows that animations are also sluggish in brave

How can this issue be reproduced?

1. Load any website
2. Scroll using precision touchpad
3. Observe lag / dropped frames

Expected result:
Should be smooth like Chrome and Edge

Brave Version:
V1.26.74 (June 30, 2021)

Additional Information:
I am using Windows 10 on a Surface Book 1 - I have just reset this device to a fresh install of windows and Brave, but still get this issue.

Just wanted to share my solution:

• I realised that I couldn’t detach the surface book display whilst brave was running, so it was using the dedicated graphics card.
• I set the graphics options in windows to force brave to use the intel cpu graphics.
• Note that I don’t have to do this for chrome or edge.

@Grid,
Great detective work – GPU issues have been kind of a pain for us in general. We have documented some of the GPU issues/workarounds we have here:
