Screen flashes quickly before playing every video

I’m having an issue with my screen flashing very quickly before starting any video. The videos I open from the web browser or the videos I play on the desktop with the player cause this problem. Below you can see the Display properties of my computer.

Can you try the following.

  1. Create/update your Firefox configuration file
  2. Install codecs (provides FFmpeg) from Clear Fraction
  3. Install the enhanced-h264ify extension in Firefox
  4. Enable ‘media.ffmpeg.vaapi.enabled’ in about:config
  5. Restart Firefox

The following tee command will refresh ~/.config/firefox.conf, supporting Intel, AMD, and NVIDIA graphics.

$ tee ~/.config/firefox.conf >/dev/null <<'EOF'
export FONTCONFIG_PATH=/usr/share/defaults/fonts

# Clear Fraction provides FFmpeg supporting VA-API acceleration.
# sudo swupd 3rd-party bundle-add codecs
if [[ -d /opt/3rd-party/bundles/clearfraction/usr/lib64 ]]; then
    export LD_LIBRARY_PATH=/opt/3rd-party/bundles/clearfraction/usr/lib64

# Using NVIDIA graphics?
if [[ -d /opt/nvidia && -f /usr/lib64/dri/ ]]; then
    export LIBVA_DRIVER_NAME=nvdec

# Otherwise, uncomment one of the following matching your configuration
# if needed. Try 'vainfo' first using the command-line. Optionally, install
# the enhanced-h264ify extension to block {VP8, VP9, AV1}.
# export LIBVA_DRIVER_NAME=i965
# export LIBVA_DRIVER_NAME=r600
# export LIBVA_DRIVER_NAME=radeonsi

if [[ $XDG_SESSION_TYPE == wayland ]]; then
    export EGL_PLATFORM=wayland
    export MOZ_X11_EGL=1

export MOZ_USE_XINPUT2=1

Do not forget steps 4 and 5 to enable media.ffmpeg.vaapi.enabled.

HW acceleration verification is possible using the intel_gpu_top or nvidia-settings utility.

$ sudo swupd bundle-add igt-gpu-tools
$ sudo intel_gpu_top (or)
$ /opt/nvidia/bin/nvidia-settings &

I experience the screen flashing very quickly using Wayland. But no flashing using GNOME on Xorg.

I use Brave browser. (but problem also same in Firefox) Also I have same problem for local videos when I play them with gnome videos or mpv etc. I didn’t experienced this problem with other distros (what i tried) on Wayland and I want to use Wayland (Xwayland).

I tried the Brave browser. It works better using GNOME on Xorg. Like you say, it flickers in Wayland. Well, I used the following steps to test Brave.

  1. Install Brave using the 3rd-party repository
  2. Obtain launch script for Brave
  3. Obtain desktop file for Brave
  4. Install enhanced-h264ify extension in Brave
sudo swupd 3rd-party install brave

git clone
cd nvidia-driver-on-clear-linux/HWAccel/brave
mkdir -p ~/bin && cp run-brave-stable ~/bin/.
cp brave-browser.desktop ~/.local/share/applications/.

I then launched Brave and installed the enhanced-h264ify extension to block { VP8, VP9, and AV1 }. Hardware acceleration works well in Xorg, although i965 works better for my Intel box (default iHD if not set).


Today, I witnessed Brave utilized the Video engine using Intel Graphics. It works flawlessly in Xorg. But drops frames in Wayland.

Thanks for help. I just run:


and it fixed. Thanks for your tactics for Brave too.
