I check in gamma stable and in 7.0-0164-gff1c9921da. It worked fine in these two.

I have further narrowed it down. The bug has started happening because of the changes done in 2025.7.0-256+6c316c2178

This change has enabled this behaviour: #1 and #2

Thanks. Should work again in upcoming builds.

Hi @Elias. Thanks for solving this issue quickly!

Seems like there’s still a bug remaining in v7.0-0285. I’m attaching a minimal repro:

egl-bug.zip (24.1 KB)

To reproduce:

  1. Open this patch
  2. Restart (using F9)

You would see an error regarding EGL.

If I delete the IOBox preview, restart vvvv and open the patch and then redo the steps, I do not see the error.

I’m attaching the error for quick reference:
