1) make sure your computer supports WebGL (updated chipset and gpu drivers) 2) make sure you didn't accidentally disable it from Troubleshooting > Application Diagnostics menu
Hello Peter van der Walt, Thanks for the information. I'm German, so my English is a bit clumsy. In the attachment you can see details of my graphics card and the setting of the application diagnostics. I have the same phenomenon on 2 PCs (Win10), the 3D View from v1.0.336 is no longer there. Also, the Check Size button is loaded despite GCode not clickable Try it now on a newer PC hardware (Win11), let's see if it works there again. Many Thanks Connie Wolfgang Scharfenberg
Will see if there is anything we can do, but it does look like a 10 year old GPU and drivers from 2015. Unfortunately Chromium maintains the GPU blacklist, as we update to newer versions of Electron, it comes with newer versions of Chromium, and sometimes a GPU/driver can get blacklisted (because their stats show it not playing nicely with WebGL based on usage reports)
