UPDATE (6/11/2018) The graphical issues with AMD and Intel GPUs should be fixed now.
UPDATE (4/2/2018) New update to the hardware renderer! Some AMD driver crashes are fixed in the latest Canary build - try it out and let us know if it helps!
For those of you who are experiencing issues with Canary builds, we are aware that the new GPU option for Shader Emulation is causing issues with some AMD and Intel GPUs. This new feature is still in review and is work-in-progress which is why it is only found in Canary, an experimental testing ground.
You may experience blackscreens and/or glitchy graphics.
The issue is being worked on. In the mean time change Shader Emulation back to CPU. You can change this by navigating to Emulation -> Configure and changing Shader Emulation to CPU in the Graphics tab.
