Event Timeline

Jacques Lucke (JacquesLucke) triaged this task as Needs Information from User priority.

Does this happen always, or just when some image/video is loaded in the sequencer? Can you prepare a .blend file that shows the issue?
Also, a screenshot/short screenrecording would help to reproduce the issue.

GPU_framebuffer_active_get in sequencer_ibuf_get returns NULL, which leads to the crash later on.
