Please
so that you are prepared for subsequent steps.
Running thru a checklist, a process of elimination, can help to clarify paths for more investigation. Yet, how you proceed, is up to you.
Usually, in a Linux OS command line, you can start Brave Browser with one of the following commands:
brave -n --args --incognito --no-experiments --disable-extensions --disable-gpu
or
brave-browser -n --args --incognito --no-experiments --disable-extensions --disable-gpu
In order to determine which of those, to use, in a Brave Browser New Window, go to: “brave://version”
Scroll down to “Command line”
The beginnings of that command line character string, will indicate to you, which of those commands to use.
The switches are intended to:
- Start up Brave Browser, showing a New Private Window
- Disable all experiments at
brave://flags - Disable extensions
- Disable GPU ie disable Hardware / Graphics Acceleration
Test your issue. Also, use another mouse for some of that testing. Double-check cable connections.
Linux OS:
The important BraveSoftware folder location, usually but not always:
/home/[username]/.config/BraveSoftware/
OR, in a Brave Browser New Window, go to:
brave://version
and scroll down to “Profile Path” - that path very likely ending with “Default” - and locate the “BraveSoftware” folder in that path.
That is a folder to be backed up routinely, IMHO.
I recommend doing that, now.
I recently had a similiar issue, and the solution was to completely un-install the Brave Browser installation.
Run some OS maintenance. Restart the computer.
Fresh installation. Restore bookmarks from a backup.
