Info block / roll over pop up are too transparent

Hakansv opened this issue · comments

Git master branch:
I think the transparency of for example a AIS roll over info has changed last week(s)
For the chart bars the increased transparency make no harm but the AIS rollover info is close to unreadable if there is chart text behind. See attached picture.
Natural this transparency is different between system. No big problem seen on my RPi or another Win.
What can have changed this behavior and can it be controlled in any way?

It seems the transparency is not the main issue here. It seems rather like the background text has change so it's shining through whatever rollover transparency is used. Could the chart text have been changed to some "foreground"? See the picture below. Land areas are behind. Chart text in foreground.
Here I set transparency to '1':

if (m_bmaincanvas)
  AlphaBlending(dc, 0, 0, m_size.x, m_size.y, radius,
                GetGlobalColor(_T ( "YELO1" )), 1); //172

Having restarted the PC all is as normal again?? Graphical card issues?
