I tested using these versions:
Stable:
Brave 1.96.59, Chromium: 154.0.8037.58
Beta:
Brave 1.97.47, Chromium: 154.0.8037.58
I tested both of those releases on two different installs of openSUSE Leap (Linux, of course).
I also use KDE Plasma … I primarily use X11 … but I did login using “Plasma / wayland” (wayland is buggy, why I use X11) to test for the issue. All works fine.
I see you’re running an older version of Stable … do you not check for updates using your Fedora system?
Oh yea, one thing I read in your last bullet point. That is VERY important information that you did not provide up top about the “version” of Brave you’re using.
You’re using a Flatpak version, correct? There is a possibility of “doesn’t work like the native installation”.
.
What we find at the Brave download / install webpage:
.
BTW … I’m not associated with Brave … simply a long-time user of the browser ( my other browser is Chrome ).
The odd thing is that the flatpack version works (when running it with --ozone-platform=x11); however, I do not use flatpack normally and instead use KDE’s discovery center.
So running with the “–ozone-platform=x11” option | argument , suggests there’s an issue on your system using Brave and Wayland.
Then the information you provided is in conflict with what you wrote for #2. In your last bullet point you wrote: " I need to keep testing: flatpak run com.brave.Browser …" states you’re strictly running using the Flatpak version.
Unfortunately, I’m a bit confused by that statement. Are you referring to the “Discover” software management application? (which has a special focus on Flatpak apps and BIOS updates).
.
Can you clarify what this statement means:
“and instead use KDE’s discovery center”
… you use it “how”??
