SUMMARY
If I use the CTRL + Alt + color picker with the keyboard I get the correct pick from only the current layer 
If I use the Wacom Tablet keys to press CTRL ALt it doesn't work. 

STEPS TO REPRODUCE

1. Assing both modifiers to the same key, select brush engine, press the tablet key to call the color picker. 
2. Assing each modifiers to two different tablet keys, select brush engine and press both keys at the same time.
3. I'm using Wacom Intuos Pro PTH-651.

OBSERVED RESULT
Result is inconsistent and any of the following may happen. 
1-After using the color picker the brush engine turns into a color picker without any key press and I cannot continue to paint. 
2- Pressing both keys fails to call the corret picker and I pick the combined color as if only CRTL was pressed.
3- The correct color picker shows up but it after that pressing only CTRL will call a "color picker from current layer only" tool as if I'm pressing both keys at the same time.


SOFTWARE/OS VERSIONS
Windows: 10 pro

I can confirm the issue, but the problem is: those modifier keys simply don't arrive in Krita's event loop, so Krita doesn't even see them. I checked with a low-level tool, but even there, the modifier keys from the wacom tablet don't show up. I'm really sorry, both for testing this out so late, and for not being able to implement a fix.

I'll have too close this -- neither with the wintab driver nor with the windows ink driver do we get the modifier key presses.
