Scrolling trouble when working with non-zero drum bank about opn2bankeditor

[Wohlstand]

Seems it's a Qt side glitch...
so, is need to refactor the ssg-eg combobox to avoid elements are needs to be hidden

EDIT: Miss looked. Yeah, it's reasonable to begin replacement with QListView thing where the visibility management is under our control (On side of PGE Editor I have made itembox model where I have made flexible filter search with categories and groups. Originally on ListWidget the thing was a bit glitchy when doing filter search with same hiding of elements. With my model this crap has gone. Seems I need to backport my thing to here and use it... I'll try to do that at evening...

EDIT I am able to reproduce the issue. Gotta look in more detail.

I'm not able to make the problem happen on my side unfortunately.
I've opened DMXOPL3-GS for a test and nothing happened.

This is not happens in OPL3-BE, happens on OPN2 - BE.

It also affects melodic banks as well, steps to replicate:

• take YM2612.wopn from https://github.com/papiezak/DMXOPN2
• select GS bank no.1, click on any instrument...
• ...and it should go down to a bottom of the list. What's weird it doesn't affect all banks in my case (for example, my Power Drumkit/GS Bank no. 2 behaves correctly

I've made some traces and don't find myself much more advanced about this issue.
It's curious how this problem happens within a delay of clicking on instruments.
(and to my knowledge there is nowhere a temporization such as timers)

One thing I found, it's maybe related with having hidden list items in the set.
If I comment the setHidden which makes rows invisible on a bank switch, the bug is not happening.

Okay, after some other works (possibly with adding of grayed blank instruments), this bug has been gone!

[freq-mod]

Well, apparently the bug is still here! It still drops down an entire list of patches:
