Preview going blank and locking up Editor

GDevelop general
1

When Previewing my game, after 1-2 minutes (it can vary some), the screen just goes blank. At this point, sometimes the Editor also locks up and needs closed out.

On a good run, Preview is a bit on the laggy side. I can live with that if I have to, but it gets really hard to test things when the screen keeps turning all black. Once, at like the 1/1 X/Y point, I got this super tiny old school sad emoji.

My game project is stored in the gdevelop cloud which may be the cause of a little lag while it pulls assets. This seems unlikely, though, as I just did a bandwidth test and I am currently pulling in 295Mbps down and 41Mbps up. With speeds like that, I doubt my pipe is any sort of issue.

Tried:
Reloading Gdevelop
Deleting THEN installing Gdevelop
web preview

The app continues to have Preview issues. Running it on the web is a little harder to say, as it runs so unbelievably slow that it is unusable.

Is anyone else running into anything like this? If it matters, I am rockin’ 5.5.245 on MacOS 15.5 with an M4 Pro (maxed out cores and RAM).

Thanks!

Thank you very much for the info! Sorry it took a bit to get back to you. Finally had a chance to look into this a little more.

I noticed in debugger that there were several invisible sprites that I forgot about and, to make matters worse, didn’t have a “trigger once” condition. So every frame I was producing +6 invisible sprites. Within seconds I had thousands and counting!

Got that under control and things are running much more smoothly. :slight_smile:
