regression in `v_native` theme

[actionless]

spotted the regression with v_native theme, not only foreground color not distinguishable but also system font got overridden:

here's with blank qss as was discussed in this ticket https://github.com/tamlok/vnote/issues/148:

It only happens in self-compiled version, right? Does AppImage have this regression?

[actionless]

i can't say because while qt5ct not works for me in AppImage — it's always default Fusion theme, not dark one

[actionless]

yes, the problem appears in both AppImage and native build

[tamlok]

It seems that qt5ct will override the qss of vnote. Just use a blank qss if you are using qt5ct. There is no better way for this.

[actionless]

with blank qss there is one small problem -- icons are not themed, so it should be smth like:

.panel .icon {
  color: @foreground;
}

but idk how exactly it should look in qss

and other, even smaller, problem, mode indicator in the bottom right

[tamlok]

You need to tune the qss instead of deleting all the stuff.

[actionless]

but can it be done in scope of v_native theme? otherwise it's not clear the purpose of such theme if it meant to be native but it's not fully is

[tamlok]

Yes. But I lack such an env to tune it. Could you help to clean up the v_native theme? It is easy to guess the meaning of the qss elements. I think you need to only delete part of it.

Thanks!
