Ubuntu Isn't Yet Recommending GNOME's VRR Option

While GNOME landed experimental Variable Refresh Rate (VRR) support in GNOME 46 that is used by the new Ubuntu 24.04 LTS release, Canonical isn't yet encouraging users to test out this option.

Prominent GNOME contributor Daniel Van Vugt with Canonical posted today in his week Ubuntu desktop status update:

"Finally got VRR set up for testing and confirmed there are two separate issues. Fixed the one that is triple-buffering specific and removed some code that doesn’t need to exist since VRR was introduced. We still do not recommend enabling the experimental VRR support in GNOME 46 because of at least one upstream bug."

So besides the fact it's experimental and hidden by default, they are not recommending Ubuntu users enable it. The upstream bug cited is VRR causing the screen to black intermittently when an application is full-screen. When a full-screen window's frame rate drops too low or idle, the monitor goes black.

Thus for now they aren't encouraging any use of the GNOME VRR option but hopefully it will be in stable shape by the time of Ubuntu 24.10 Oracular Oriole in October with GNOME 47.
