Please can you provide a blend file to test?

It doesn't happen in Ubuntu 18.04, all works fine, but it doesn't work on Windows

Blender 2.78 is old, you should download Blender 2.79b from here:
https://www.blender.org/download/

Left: 2.8
Right: 2.7
This limitation is present also in 2.7

Yeah, it does get weird results in your blend.
However, i tried with the latest build of today's 2019-02-18 and it seems to work properly now:

I can confirm, it is shifted

I confirm, it crashes

Please try this:

• enable contact shadows in the shadows tab of the light properties panel
• change the shadows method from ESM to VSM in the shadows tab of the render properties panel

This method will reduce the ghosting of the walls.
Also enable High Bitdepth and Soft Shadows to remove the ghosting even further

Please provide a detailed description of the crash, specify the exact steps to reproduce it and specify if you are using Cycles or Eevee and maybe provide also a .blend file so we can test it.

It works for me

Please try this: go to File and click Load Factory Settings. Then try to see if this worked

1. This is the Particles.blend file where i saved a particles system and assigned to a plane:

2. Open a new project, go to File > Append and choose the "Particles Test" ParticlesSettings from the blend file above:

3. Now add a plane, go to Particles Settings and choose the "Particles Test" particles system from the list

4. Switch to Cycles render, and enter in rendered mode for the viewport... CRASH

ok thank you

And for empty.001 you had just the Display Orthographic option enabled.

I think they fixed it

Thank you guys!! I was really needing it!

Not a crash but a render error:

This is a file with a particles system: note the grass strands are in a collection called "Bahiagrass":

I confirm!
I add an HDR in the LookDev HDRI's panel:

nope

I found the solution!
In the Children tab, under the Clumping sub-tab, you have set the Clump value to a negative value.
Set it to 0 to get all the grass the same size.

What Blender version are you using?

Mine get antialiased...

Yes, he disabled the overlays:

You are using an old version of 2.8 (2.80.40). Please try again with the latest build of 2.8 that you can find here: https://builder.blender.org/download/

Yes, it makes more sense: 0 vertices in a scene full of vertices doesn't make sense, so i like the way 2.8 manages that

There are some themes in Blender 2.8, some are near the Maya looking one.

Please provide a screenshot of the case.
Try to change the transparency mode in the materials panel from Opaque to Alpha Blend.

Still getting the error with today's build 38984b10ff7b

I found the solution! I just did Reload Factory settings and tried again, and now it appends the objects and not the emitter.
But, Blender appended the 3 objects in the main collection, which is not good because if i now just add a Plane and add that appended particles system, save the file, quit and reopen, the collection is gone in the render tab of the particles system.
I think that appending a particles system would work better if the collection is appended not as fake user, but as a real, and most important, SEPARATE collection (if that makes sense).

Nope.. i tried again the same process, and it appends also the plane (emitter).
And when i save the file where i just appended the particles system, then close and reopen, here is what happens:

You can't use the math node between two vector type (purple color) nodes. That's why it doesn't work. If you need to multiply the strength of the bump, just place that multiply node in between the Noise Texture node and the Bump node.

Yes please, fix it, i need high res shadows cubemaps

I'm using the latest drivers from AMD because otherwise, with the default AMD drivers in Ubuntu, i couldn't render in Cycles using OpenCL.
This is the driver i'm using: https://www.amd.com/en/support/graphics/radeon-500-series/radeon-rx-500-series/radeon-rx-580
This is the output of my terminal when i run glxinfo | grep "OpenGL version".

The solution to this problem is here:
http://artificialflight.org/blog/2013/cycles-crash-cuda-tdr-error/

Jacques, the drivers of my AMD RX 580 are up to date to the latest from the official AMD website (version 18.50) and the Blender version is the one from today (i wrote it above).
The crash happens if i am in the rendered mode in the viewport and if i change the cube size of the shadow to 1024px or above, it doesn't crash if i choose 512px or lower.

Where is this option? I want to get rid of the color bendings

ok sorry.

This is the Info File:

1. The Drivers are the latest.
2. The problem happens with any scene.
3. Yes, the problem happens both in viewport and in F12 renders.
4. Where is System-info.txt file located?
5. How to run Blender with this command line?

Nono. It is the 7400M Series AMD Radeon HD graphics card. And the OpenCL Kernel says: "the first time it require a long time" and after 2 - 3 minutes it reports an error: "opencl kernel failed" please, if you can resolve this bug

System Information
OS: Windows 10 (10130)
Graphics Card: AMD Radeon HD 7400M Series

Sorry, this is the Image
