I am working on adding a test to ensure Weston repaints damage correctly, where I rely on Weston repainting exactly and only the damage submitted by a client. That means I have to stop screenshooting from damaging everything automatically. Doing that, I noticed that screenshots on DRM-backend could theoretically get stuck if I do that. So test for it.
