I do not know if it is allready a topic if so I am sorry please delete the topic. I quite often get if I am changing or adding an image to a sprite that the instances editor rendering chrashes. I save the work reopen the extension that it happend in and it all works fine again. This is the error. I am running on Windows 11.
I’ve seen the instances editor start rendering oddly after GPU driver updates before, especially with hardware acceleration enabled. Sometimes just toggling the rendering option or clearing the editor cache fixes it without needing a full reinstall.
After the last Gdvelop update I did not have the problem anymore
