What steps will reproduce the problem?

Hi!

I’ve noticed something strange with the key press detection.
When I press the Control and Shift keys, some of the keyboard keys are not detected.
For instance Ctrl+Shift+J does not work. Same for K and 0 (zero).

It’s actually easy to reproduce when running examples/keyboard, and pressing Control, Shift and J at the same time.

What is the expected result?

I expect the 3 keys to light up at the same time: Control, Shift and J.

What happens instead?

Only 2 keys light up: Control and Shift.

Anything else you feel useful to add?

That’s with a QWERTY keyboard layout.

I couldn't reproduce the issue on Windows (Parallels). I feel like this is a hardware-specific problem.

• Could you give me more details of your machine?
• Would another keyboard reproduce the issue?
• Would this issue be reproducible with other applications than Ebitengine?

Hmm, I tried on another Windows laptop, and there both J and K work, but Control+Shift+0 still don’t.
But then I opened Goland and tried that combination of keys in Keymap / Find Shortcut, and it too doesn’t get the exact same combos of keys!

Sorry for the noise, there must be some application that has defined system wide shortcuts, or something.
