Not resetting properly (artifacts) with button

[brunogm0]

It shows artifacts after reboot with just primaries change... then tried reseting in many ways and it was not effective until loading a ICC profile like 709 reference or any other.

Can you reproduce the buggy reset behavior by setting both source and destination primaries to "Default", or "sRGB"?

[brunogm0]

with sRGB in both i cannot trigger the artifact but once its triggered (input sRGB output AdobeRGB, apply (still normal screen) -> reboot; Then from login screen everything goes crazy colors).

Then app reset or setting both input /output to default or sRGB do not fix it.

Also tested loading icc to fix artifacts then clicking reset button the artifacts return.

I have reproduced the issue. Seems AMD finally added reboot persistence for regamma LUT but broke the parametric curve option.

Further analysis:

• Applying regamma options other than LUT on boot (done by the driver) is broken.
• Setting a regamma option identical to the current one will be a no-op and won't fix incorrectly applied LUT.
  • The reset button doesn't remove persistent settings. It just copies the default settings that I grabbed from a new display.

Possible workaround: load regamma LUT from sRGB ICC profile if identity gamma transform is desired.
