Hi zvacet, sorry to get to you so late.
Of course, you can do as you think best.
You did what I would do, as adding 'solved' to this thread. But if it were me, the official bug report should stay open and include how you temporarily fixed problem by describing how you edited a file. I call it a 'fix' and not solved. Solved is when you don't have to edit or change a file, but instead and update from the developers or a new release solves the problem without you having to edit a file. That way the problem is solved for anyone that has your similar hardware, too.
See you at the pisilinux forum
