I was trying Xenko on my SP3. However, as you can see from the image below, the scene viewport is displayed incorrectly.
This is a known issue (see #464). Which OS version are you using on the Surface Pro 3?
Oh sorry about that. I am using Windows 10.
Afterwards, I noticed that problem on my main desktop PC. I think it's because on the SP3 the zoom level was set at 150%. Some game or multiple screen setting must have (temporarily) altered that on my desktop PC too.
I have also noted another problem, but I am not sure if it has already been reported. It's about shaders, I tried to search the open issues but I haven't found any reference. Basically if a shader is supposed to return a color, and it is not returned, the mesh disappears but I can see some polygons flashing in and out. In some more severe cases the editor goes in full seizure mode and starts flashing on and off very rapidly. If this has not been reported yet I'm happy to open a new issue.
Just to be sure, is this the anniversary update?
I noticed this too: Anniversary update, Surface Pro 4
This is my screen:
I look forward to using Xenko but it's very hard on this computer like this
Note that if you open Explorer where you installed Xenko, look for the folder GamePackages\Xenko.1.8.3-beta\Bin\Windows-Direct3D11 (replace 1.8.3 with your version of Xenko installed), thrn open the Windows properties of Xenko.GameStudio.exe. Make sure to check Disable display scaling on high DPI settings in the compatibility tab.
Disable display scaling on high DPI settings
Then relaunch Xenko. It should be fine with the downside that the UI elements would appear quite small.
Thanks for the workaround. Will this be fixed in the next release?
