High DPI scaling messes up placement of breakpoint red circles

[DStauffman]

The breakpoint red circle is drawn between two lines instead of on the relevant line when high DPI scaling is on.

What steps will reproduce the problem?

1. Use 4K or other high DPI monitor with scaling turned on (may be unnecessary, I don't have an old one to test right now?)
2. In general preferences, check "Enable high DPI scaling"
3. Restart Spyder to enable high DPI scaling
4. Place a breakpoint in a file

What is the expected output? What do you see instead?
The red circle should be nicely centered on the line with the intended breakpoint. Instead the circle is drawn about half a line high and it is unclear which line it corresponds to. Further, trying to turn it off often accidentally leads to turning another one on, but offset from the line you intended.

The breakpoint shown below is intended to be on line 8 with the command "pass", but shows up between lines 7 and 8.

Note, that turning off the scaling fixes the alignment, but then you are stuck with really small icons and circles.

As I'm looking at this more, I noticed that it also happens for things like the orange exclamation triangle for code analysis issues.

Thanks for reporting. We'll at this one after we release Spyder 3.2
