Fullscreen causes stutters and flickering in viewport

Short description of error

When fullscreen (Window > Toggle Window Fullscreen) is used, lots of stutters, flickering and lag happens in the viewport. Especially when moving the viewport around.
This ONLY happens in Window > Toggle Window Fullscreen but if I go windowed mode and maximize, the issue goes away.

This has been an issue in the new Blender 2.8 viewport since I can remember so it is nothing new (for me at least).
I have tried recording a video of said issue but my screen recorder didn't pick it up.

Hope this helps!

Can you try out a later blender beta version and additionally if updating your GPU drivers helps?

If that doesn't help, report back here and we'll see what we can do.

Hi Sebastian thanks for replying.

I have updated my graphics drivers from Nvidia Experience to the latest one and I used the latest Blender 2.8 beta build from december the 10th yet the issue still persists I'm afraid.
Are there any other steps I should try?

You can try running blender with "--debug-gpu" and attach a file with the output here (DO NOT paste the output into the comment section)
And you could also try if "--debug-gpu-force-workarounds" help solve the issue.

@Clément Foucault (fclem), I do not get any rendering artifacts when I try to reproduce this, but I seem to get lower fps (IE the cube doesn't spin as smoothly when I rotate the default view). I'm on linux though and using a AMD 290x...

I'm sorry, I'm not very tech savvy. How can I save the output from cmd into a text file?
Thanks! > textfile.txt doesn't output everything

I do not know how it should work on windows but it that way as described here:
Does not work, then I do not know. I guess you could try to copy paste the output manually?

Manually you can : Click + drag in the console to highlight selection . Then right click. The selection disappear and gets copy to the clipboard. Just Ctrl+V in a text editor and save file for upload.

Thanks guys, I manged to save it into a file

Also I would like to add that --debug-gpu-force-workarounds didn't work sadly.
