Eplieptic Graphics Overload

[nyghtly-derek]

System information:

Description of bug:

The application's graphics immediately malfunction upon opening, blinking excessively between many different colors.

The loop can be stopped by pressing L. After that, the application works correctly, allowing the user to draw and delete lines, etc.

I believe this bug is probably specific to Windows 10.

A simple way to prevent this bug might be to clear the screen in between drawing loops, or to clear the screen immediately upon opening the window.

Thanks so much for reporting the bug! I'm trying to reproduce it on my windows machine...

@Liby99 I have access to another Windows machine--I'll try and reproduce it on there as well.

@nyghtly-derek Hi! I have also tried reproducing on my Windows machine. Though I once saw some weird cyan colored canvas when sketching on it, I cannot reproduce it anymore.

I think this is an upstream library bug regarding back end/GPU, and we can do so little.

I also released an alpha build for Windows x64, you can test it. We very appreciate for your feedback and bug reporting.

Just tested the master branch on my other windows machine. No graphics glitch detected this time.

Here are the specs:

Worth noting that the computer with the glitch was using onboard intel graphics whereas this computer has a dedicated graphics card.

Might be worth reporting this upstream. I assume Piston is the relevant crate?
