Description of the issue:

  2. In normal screen mode, video plays without lag or frame dropping
  3. When switching to full screen mode, video begins to lag and drop frames.

Expected result:

Video should play in full screen mode without lag or dropping frames. Other apps such as Amazon Prime and VLC, have no issue playing video in full screen mode.

Brave Version( check About Brave):
Current version

Additional Information:
Using Task Manager and Resource Monitor, there is not an indication of computer hardware limitation. The issue occurs at every video resolution. (typical resolution is 360p or 480p).

Good report, but you would help your cause, by editing your Original Post (“OP”), above, to include the:

  • Windows OS version
  • Computing device
  • Brave Browser version

A way to gather that info, is to, in a Brave Browser New Window, go to:

brave://version/

Copy the first four lines 1, 3, and 4 of that page, and use that text in your OP.

Example from my old Mac computer:

Brave: 1.41.100 Chromium: 103.0.5060.134 (Official Build) (x86_64)
OS: macOS Version 10.12.6 (Build 16G2136)
JavaScript: V8 10.3.174.20


And, you might run some tests, by searching through the Brave Browser Settings, to find the switch that Enables / Disables Hardware Acceleration . . . and disable that.

This is Windows 10, most current version. Brave is also the most current version. Desktop computer that is fully updated and has separate video GPU card.

I have already tried the hardware acceleration options, in both Windows and Brave, and updated drivers. It makes no difference.

As noted, this does not appear to be a hardware issue, based on monitoring the CPU threads and other video players.

I have read online that Chromium based browsers in general have this issue. I’ve tried it in the Edge browser and the same thing happens.

Something is overloaded, and whatever manages the computer display, is paying for that.

Be prepared. Back up your:

  • tabs (as bookmarks)
  • passwords
  • bookmarks

Clear cookies, cache, history, etc.

In a Brave Browser New Window, go to:

brave://settings/clearBrowserData

Select the Advanced tab

Set Time range to “All time”

ENABLE everything except:

  • Passwords and other sign-in data

(Myself, I would NOT make that exception)
(because I would have a backup prepared.)
(In other words, be prepared.)

Click on the “Clear data” button


In a Brave Browser New Window, go to:

brave://flags/

Click on the Reset all button.

Quit everything and restart your computer.

Disable any extensions that you have added.

Nothing is overloaded. The computer has just been rebuilt and as noted, there is no indication of resource shortage in the Windows Task Manager or in the Resource Monitor.

Enjoyed reading the article above, really explains everything in detail, and the article is very interesting and effective. Thank you and good luck with the upcoming articles. Great post. It was much needed. Love your simplistic style of explanation.
