Title:
Gnome resizes framebuffer when playing fullscreen video over and over
Vlad,
So, when full screen videos or games are played what we do is disabling
the down-scaling everywhere (as to scale at 150% we've to scale
everyting at 200% and then scale it down again), not to affect the
performances, however this could be probably applied just to the monitor
that is
Thank you for your work on the issue. How can I update to the new
version? I ran all package updates and upgrades in Ubuntu, but my
version of mutter is still 3.43.3.
Regards

Thank you for the fix!
After having my mutter updated, I can finally watch the fullscreen videos while
having the fractional scaling enabled
However, there is one minor issue. Whenever I switch to the fullscreen
mode, the scaling factor is changed from 150% to 200%, so all the
widgets are
This bug was fixed in the package mutter - 3.36.1-3ubuntu1

mutter (3.36.1-3ubuntu1) focal; urgency=medium
* Merge with debian, with new upstream releases and cherry-picked fixes:
- Screens turn off when setting display scaling to 200% (LP: #1869750)
- Use hardware
@jonas-jelten I believe that should be it

Please don't discuss screen tearing here. That is bug 1846398 and/or bug

Title:
Gnome resizes framebuffer when playing fullscreen
The screen tearing that I mentioned happens when playing videos in VLC
and mpv Media Player (with 150% fractional scaling). It occurs when
using the applications in windowed mode (since fullscreen mode causes
the resolution switching bug). I'm assuming the same problem will also
occur in other

I'm having the exact same issue, it's also caused by 150% fractional
scaling in my case. I'm also noticing a lot of screen tearing when
playing videos. All problems (resolution switching and screen tearing)
disappear when I revert the scaling to 100%.

Okay...so there is hope to get this at least "bypassed" for 20.04 - this
would be awesome!
btw: before this became a regular problem (don't ask me when - but I
didn't have this problem some 2-3 month before), I had this effect when
I detached my keyboard from my 2-in-1 Toshiba z20t-c.
It sounds like fixing this bug is the least difficult issue. It also
sounds like you should subscribe to bug 1825625.
Your suggestion of a workaround for this bug is not necessary because
with the same amount of effort we could just write a patch to disable
fullscreen unredirect during fractional
Hello Daniel,
I'd love to use Wayland - but the graphics are worse. Even in unscaled
mode, there is horrible text-rendering and when scaling, some apps go
blurry (I know,that this can be handled for e.g. firefox - but there are
other apps, which aren't "fixed")...
Would it be a workaround to
Though if you use "Ubuntu on Wayland" then you need to set:
gsettings set org.gnome.mutter experimental-features "['scale-monitor-
framebuffer']"

That would probably be because a window in the foreground prevents
fullscreen unredirect from being used.
I suggest if you need both fullscreen window support and fractional
scaling then logging into "Ubuntu on Wayland" might be a better option
right now.

I'd like to add that the problem doesn't occur, when there is another
(pinned) window in the foreground! E.g., open a terminal and make it to
stay "on top" and the video plays fine in fullscreen mode (behind the
terminal).
