Expected Outputs
No error messages.

Reproduces how often:
Always

Brave Version:
1.11.104 | Chromium: 84.0.4147.105

Reproducible on current live release:
Yes

Additional information:
I’m using Fedora 32, under Gnome on Wayland.

try to turn of hardware acceleration and sync and disable all extension then try it again
if it work then start to enable them back one by one till you get the cause

i am using centos no error show up here

hope that help and have a nice day

At brave://extensions/ extension Fedora User Agent, which is present by default and alone in that page, was disabled. Though at brave://settings/ others extensions are gathered. There too the ones enabled were disabled., same applied to the hardware acceleration. Unexpectedly there is no link related there or in the interface to synchronization. Since I’m not logged in that service I assumed it has to be by default disabled

Here is a sample of an output:

$ brave-browser
MESA-LOADER: failed to retrieve device information
MESA-LOADER: failed to open i915 (search paths /usr/lib64/dri)
failed to load driver: i915
MESA-LOADER: failed to open kms_swrast (search paths /usr/lib64/dri)
failed to load driver: kms_swrast
MESA-LOADER: failed to open swrast (search paths /usr/lib64/dri)
failed to load swrast driver
Failed to parse JSON adblock resources: EOF while parsing a value at line 1 column 0

do you have nvidia card ?

No, the model is Dell Latitude E4300 (year 2009).

that’s wierd i looked in the internet and all those error related to video driver but the weirdest that your device does not have even the i915 intel

i think it’s related to video driver issue try to google this line failed to load driver: kms_swrast
most of the search result talk about mesa-utils and libgl1-mesa-glx liberary

check also if your os is updated

hope that help and have a nice day

I executed dnf --refresh -qy upgrade in order to ensure my system is up-to-date. I did not get that time the previous output. Nevertheless all the outputs that are in the original report are still relevant.

sorry idk the reason as it looks like it changed the error as you said that the last error disappear even you did not change anything
