To enable HDR in Windows 10, and start by opening up your Start menu and going to the Settings app.

From here click on “Display,” and you should see a toggle below the Night Light option that reads “HDR and WCG”

I too have this issue, when I turn off HDR in Windows 10 the mouse cursor returns to a white cross however with HDR on the mouse is small, black and hard to see against the background. Please resolve this issue so I can Blend with HDR on!

I don't currently have hardware that supports HDR, but I would LOVE to have someone who does - and who compiles Blender from source - to test if this issue is changed with this:

https://developer.blender.org/D5197

The above requires applying a patch and placing some cursor files in a location (the link has a zip for those, scroll to the bottom of the comments). Once applied almost all the cursors shown in Blender while on Windows will use a different and newer format that support multiple resolutions and antialiasing. My gut feeling is that it will fix this issue, but it would be important to know if it does not.

Hi Harley, thanks for the quick reply.

I've tried to compile the latest build with the new mouse cursors supplied by duarteframos however I'm not sure what I'm doing and it hasn't fixed the issue. I've moved the cursors to the folder "blender\release\windows\icons" as advised however I cannot see a patch to apply. I've then compiled the latest Alpha version V2.81 which works but still with the dark Edit cursor mode.
Here's a couple of pictures, the first version is with HDR on and the mouse cursor is black and hard to see, second picture has HDR off and has a clear white cursor.

Hey @Bones88s, Thanks for giving it a try.

You did the part that I was worried people might miss, copying the contents of the last zip in that thread to "blender\release\windows\icons".

The next part is applying the patch. That link , at the top-right has a "Download Raw Diff". Clicking on it will fill your screen with nonsense that you can save your to your harddrive somewhere. Lets assume you saved it as "D5197.diff" to the root of your "blender" folder. You can then be at a command-prompt in that folder and do "git apply D5197.diff" and it will alter your source with my changes. Then compile and you should see new cursors. Later you can run "git reset --hard" and my changes will be gone.

Ok, so I managed to apply the patch and recompile and it works!!!! I now have a white visible mouse cursor when using HDR and Edit mode in Blender 2.81 Alpha.

Thanks so much for the prompt reply and help with the patching. A good learning experience for me and I can now get on with learning Blender again!

Hi again,

The only issue I can see now is the new build (2.81a) doesn't recognize my GPU in Preferences->System->Cycles Render Devices, whereas the official 2.80 build does. I've downloaded the CUDA 10.1 as advised by these instructions https://wiki.blender.org/wiki/Building_Blender/Windows#Quick_Setup.

Any idea how I can compile the latest build so I can use my GTX 1080 GPU fully?

Thanks again Harley

Hmmm... that’s going to get complicated...

First I should explain that this process you went through was awesome for me, and for the Blender community as a whole, because it confirmed that this work I have in progress will fix the problem you’ve experienced. So thank you very much!

But compiling blender like this would not generally be a way to make version of blender that you do real work on. Normally you would do this in order to make changes and improvements to the source code that you could then send to Blender so that it can improve.

So this patch won’t be very good for as a specific fix for you unless I can get it finished and through approval quickly so it can be made a regular part of blender.

Because building blender as you did is meant to be a developer process, some things are turned off by default. Especially pieces that most devs won’t specifically change. Which is why you don’t have CUDA. That can be enabled, and there are further instructions for doing so somewhere but I have never done it myself.

So in summary, what you have mostly done is helped me confirm a problem and that will eventually help everyone. But you, specifically, are not much better off. For real work in blender I would recommend using a regular install and turning hdr off until we get a fix in.

As I'm thinking of moving from Maya to Blender its not that important to have HDR on while I will continue to learn the basics.

I'm glad I was able to repay your quick response by helping you out a little and thanks for the clear explanation regarding the building process. Its been a good learning experience and I already feel like I'm a small part of the Blender community!
