Colour profile is ignored on external monitors

[AlexanderOcias]

Colour profiles are only correctly used on the first screen, when Aseprite is on an external monitor, it will ignore colour profiles.

For example, to easily see the difference, changing the native screen's profile to the lower gamma "ACES", results in a correctly darkened Aseprite (both screenshots matched to sRGB for clarity):

Native Screen

When doing the same on an external screen, Aseprite ignores the profile change and stays bright:

Yeah 👍 something in my to-do list for the final version is support for multiple monitor with different color profiles (when we move the window from one monitor to another, the color space can change, so we've to update the surface).

You can check if moving the window to the other monitor, and resizing the window does update the color profile correctly. The same when you change the color profile, but it might not work anyway (I think the color space is taken from the main screen only, not the display where the window is located)

Thanks decap! I experimented and found a temporary workaround to be to put the 'primary menubar' on the display you DON'T need the profile to work on, like so, in this setting:
