MacOS Catalina Bug
-
@testesttest8889 I confirm, Flux doesn't work correctly on my MacBook Pro 13-inch 2019 with Catalina OS. It flash and look very weird... Closing flux and everything return to normal...
-
Can someone also test turning off True Tone? A conflict there would make sense, since it's only on the newer models.
-
2018 MacBook Pro 13-inch with Catalina OS and True Tone off still causes the flashing and colors/temp to look off
-
Yep, True Tone is disabled.
-
Same issue here. Flux also causes OSX to prompt to grant screen recording permissions. I suspect the latter is just due to the API it uses, but perhaps failing to grant it is what's causing the problem?
-
This should only be in the about box, which we use to estimate screen brightness. Could add a button you'd have to push if it's too alarming.
-
F.lux didn't work for me either when I installed Catalina, but when I ticked "true tone" box it started working normally again.
-
Anyone with "Feedback Assistant" please send a note to Apple for us?
Has to be done on a machine that's affected, and we haven't bought a new MBP yet. :)
-
Just a small report from me - everything works now. I haven't changed anything nor updated something, yet it started to work normally again. Maybe this is only in the first few hours after upgrading?
-
@_paul Okay so maybe this is a True tone conflict, it just takes some time to actually turn off?
-
Still experiencing same problem, turning of True Tone/Auto Brightness didn't help
-
For me it works when my external display is plugged in. As soon as I unplug it everything starts flickering and the color filter is only showing around the UI elements, on and off.
As other mentioned, True tone and auto brightness don't change a thing.
-
Just for the record, I highly doubt this issue is related to f.lux. As far as I can tell, f.lux is simply feeding a color profile to macOS, and there seems to be a general color profile issue going on in Catalina.
I have custom monitor calibration profiles (from a calibration device), and macOS randomly ignored the profile. As far as I can tell, most of the time, macOS decides to apply the color profile correctly for everything except for pure white. #fff is always rendered as #fff, even though the color profile might tint it differently. In f.lux, this is especially harsh since everything white will glow really bright next to the red'ish colors.
I have reported several issues in regards to color profiles in Catalina via the Feedback Assistant.
-
Same issue on MBP 15,4. Haven't yet noticed the problem on iMac 18,3 with additional external display.
For what it's worth, a system restart fixes this bug for me, at least until a subsequent sleep/wake cycle. (Merely restarting f.lux does not fix the bug, though obviously the flashing effect ceases when f.lux is disabled.)
-
In case it helps this is happening on my macbook pro since installing Catalina. It also happens with another similar app called Iris.
-
Have true tone disabled, have night shift disabled, and no external monitor. With flux running the screen flickers and changes color on a regular/random basis.
Have the issue with both stock and custom profiles. It's definitely a flux/catalina incompatibility. Now, on who's end I can't say :-).
-
any update on whether this will be fixed?
-
@bnodvin we do not have a workaround.
As above, anyone with "Feedback Assistant" please send a note to Apple for us?
-
And it's back again after installing the latest update. :-(
herf: Any way to get that feedback app without being a developer?

I'm seeing this issue as well. In case it's helpful, here's a short (1 min.) video to give you an idea what's happening. As you can see onscreen in the video, both True Tone and automatic brightness are already disabled.
