Failed to restore previous EGLContext

vvvv gamma bug
1

I recently encounter this error quite often. It is happening across different patches and using different rather recent Previews of vvvv gamma. I cannot really reproduce it so far. What is happening is that all Skia Windows including the vvvv UI are crashing showing the known red cross on white background, while StrideWindows are still running and stay interactive. Is this happening to anybody else?

I am using Windows 11 with a i7-12700 and a 4070Super.

Exception: “Failed to restore previous EGLContext. A power management event has occurred. The application must destroy all contexts and reinitialise OpenGL ES state and objects to continue rendering.”

Hey, yep, seen that one quite often, most of the time when the computer wakes up from sleep. Your error log mentions the following:

Can you relate to that?

ah yes forgot to mention this, but it never happens after the computer wakes up, but usually during patching.

Newest previews should handle a graphics device loss better - can you give them a spin and report back please?
