found whats causing the bug, its when i press 4 keys at the same time, diagonal movement + jump + shoot, but only on gamepad.

Interestingly... issue only happens on windows.
The issue is that you maybe press the left thumbstick down while going diagonally, which should show the map... but opens menu instead. Works fine on linux.
Also, on windows, doesn't show the buttons to press when gamepad is inserted, while it works on linux, again...
So many people missed that part xD
Need to look into that.
