Hi everyone,
Newbies here. Trying to move from Windows to Linux. Tried a few distro in the past few weeks and decided to keep F42 for its usability and elegance.
But one thing bothers me.
- I use a LG Gram 17 with Intel 258V CPU with integrated ARC graphics, pretty new one.
- Original Gnome desktop environment from standard F42.
- When I use browser (tried Firefox, Vivaldi) to view any page, if I trigger the full screen mode (usually with the F11 key or through menu), the lower 2/3 of the screen starts to flicker on mouse move. Video here.
I use the function to get bigger screen space when working on Office365 Web. I’m a bit old, bad eyes…
- Tried updating the mesa driver. The update seems successful but takes no effect to the issue.
- It seems to happen only with Fedora+Gnome on my hardware. F42+XCFE and Manjaro+Gnome don’t have this issue. But I prefer F42+Gnome’s newbie-friendliness and elegant look.
Tried to crawl over the internet and also did a few days of frustrating ChatGPT-ing. Ended up asking for Guru’s help here.
Any suggestions will be much appreciated. Thank you so much!
Welcome to Fedora @phineas0724
Xfce and Manjaro gnome are probably still on x11?
Give a try to run gnome without extensions, to see if this changes something? While starting the Extensions app you can generally disable them. If this gives a positive change try to activate one extension after the other to see which one it could be.
If this not helps, you could give us more information about your system, to see which GPU drivers are loaded.
inxi -Fzxx would be a good choice for that. You can execute it in terminal and past the output here as pre-formated text </>.

Thank you so much for the feedback. Tried to turn off gnome extensions and the issue remains.

Also I’ve found that the flickering only happens on the laptop screen.
If I connect the laptop to an external screen and work in joined display mode, sending a browser window to the external screen won’t flicker on full screen mode. But bring the browser back to built-in screen then it happens.
The issues doesn’t happen in neither external display only nor mirror mode… Hope this gives more clues…
Many thanks again!
Do you have options on the “Refresh Rate” in the gnome settings?
Is the scale factor higher than 100%?
If one of this options above are causing the issue you should put to default and try with resizing the font instead of changing the scale factor as an example. There is the gnome-tweaks app you would need to do that.
