Jagged lines in 6.0.901.0

[astrodavid10]

Version 6.0.901.0 shows jagged lines upon opening the application that resolve themselves with a window resize.

I see that you found the work that I've been doing towards automating release builds! @Carifio24 will take a look at this. Is this issue happening on a HiDPI display?

[astrodavid10]

Yes! And also yes, 4k monitor, although with Windows scaling it is 2560 by 1440

[Carifio24]

I would guess that this is a resolution/display-based issue, since I'm not seeing this on the monitors on my machine (neither of which are HiDPI). I'll see if there are any settings I can tweak to try to reproduce this.

HiDPI and the modes are a difficult challenge. I can take a look at this and see if I can create a workaround to cause a immediate rescale on startup to let DX know the DPI scaling is in place. I think it has to do with initialization flow in the HiDPI scaling on startup.

I've been trying to look into this, but without access to a HiDPI monitor it's pretty difficult to test anything out.

If a window resize makes the jagged lines go away, would calling OnResize(EventArgs.Empty) in the Earth3d constructor (or maybe Earth3d_Load) do the trick? Obviously it would be nice to find a real fix, but if we're somewhat pressed for time, maybe that's a workaround.

[astrodavid10]

This was an issue in the past #131 and #132

[Carifio24]

Here's a build with a call to OnResize(EventArgs.Empty) at the end of the Earth3d constructor. @astrodavid10, could you (or anyone else who has a HiDPI monitor) try this out and see whether it fixes the problem?

@Carifio24 This checks out for me - no more jagged lines!

[Carifio24]

Great! Then we can use this workaround until we come up with something that more directly addresses the root cause.
