G'day.

I just installed 1.39 and after maybe 10 mins of running it crashes with these errors. What can I do to assist troubleshooting?

Hi W3WTW,

The error report that you provided shows an exception in the Intel graphics driver, igxelpgicd64.dll. The most likely cause is a buggy or mismatched Intel driver. Version 32.0.101.6452 shown in the report is one of the Intel drivers that have a history of OpenGL crashes. What you can do:
  • Update — or roll back — the Intel graphics driver. Get the latest from Intel directly (not Windows Update). If you are already on the latest, roll back to a known-good older branch. 
  • If this does not work, force SkyRoof onto the discrete GPU if the machine has one: Windows Settings → System → Display → Graphics → add SkyRoof.exe → set to "High performance." That routes rendering to the NVIDIA/AMD driver instead of the crashing Intel one.
  • The last resort is to fall back to software OpenGL using the Mesa workaround as described in the FAQ section of User's Guide: drop the Mesa opengl32.dll into the SkyRoof folder. CPU-heavy, but it bypasses the Intel driver entirely and will confirm the diagnosis: if it stops crashing with Mesa, the Intel driver is definitively the culprit.
