On Windows 10, Acer Quick Access ignores system color profile

On Windows 10, Acer Quick Access ignores system color profile. For example:
- go to colorcpl.exe, install some ICC profile and set it as default;
- reboot the PC (or log out) and look at your screen color changes while PC is booting;
- you can see that Windows successfully loads your ICC profile, but then, in 1-2 secs, Acer Quick Access drops screen color to its default value (or to yellowish if Acer Bluelight Shield is enabled). Formally your ICC profile stays enabled in colorcpl.exe, but it doesn't actually work until you re-enable it manually.

I think this is a bug. The issue is present even if Bluelight Shield is disabled. The only way I found to resolve this issue was to disable Quick Access autostart.

 

This makes Quick Access almost unusable for those who use ICC profiles.

The issue was not present in old Quick Access versions for Windows 8.1 (without Bluelight Shield).

Posting here in addition to the support request.

Two months have passed, nothing changed. Acer didn't hear us.

 

Meanwhile I found temporary solution for this bug:

- Open Task Scheduler (taskschd.msc)

- Find the task named "Calibration Loader" (Task Scheduler Library -> Microsoft -> Windows -> WinowsColorSystem)

- This task has two triggers, you have to edit both of them and set delayed start ("Delay task for up to..." - set 10~15 seconds, or more if your system has many autoloading programs)

 

Now Windows calibration loader starts after (not before) Acer Quick Access and successfully loads my color profile.
