reaper.BR_GetMouseCursorContext_MIDI() noteRow_value BUG with scale>1

[olshalom]

While reaper.BR_GetMouseCursorContext_MIDI() does start to return noteRow_value ~ -1 at the correct height, it doesn't start at the correct noteRow.

The Issue appear with a scale>1 on windowsOS.
On macOS it's working correctly. No clue about Linux, sorry.

The offset stays the same, even ccLanes area get changed in height.
So it seems to me the height of the transport/grid settings bar and the scrollbar is not scaled correctly.

All other values (ccLane, ccLaneVal, ccLaneId) seem correct:

-- CONSOLE OUTPUT --
function Msg(param)
  reaper.ShowConsoleMsg(tostring(param).."\n")
end

function main()
  reaper.ClearConsole()
  local scale = select(2, reaper.ThemeLayout_GetLayout('tcp', -3))/256
  --Msg(scale)
  local window, segment, details = reaper.BR_GetMouseCursorContext()
  local retval, inlineEditor, noteRow, ccLane, ccLaneVal, ccLaneId = reaper.BR_GetMouseCursorContext_MIDI()
  Msg(segment)
  Msg(ccLane)
  Msg(ccLaneId)
  Msg(noteRow)

  reaper.defer(main)
end

reaper.defer(main)

I ran into the issue by debugging the super cool "Lasso for midi editor" script by Amely Suncroll:

Thanks for looking into the issue to satisfy all users of the script.

I agree with that. If we have 125% scale on windowsOS then we get row offset +1 compare to 100%. If we have 150% scale then we get the row offset +2 more compare to 125% scale.

100%

125%

150%
