Red Screen After Closing Shotcut

What is your operating system?

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?

Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)

Whenever I close Shotcut, a bright red screen pops up and then goes away. This has been happening for a while now.

Sorry, I have never seen this. I doubt I can do anything about it. What problem does it cause besides being ugly for a second?

Usually, If a screen pop up comes on my monitor it is blue. If a screen pop up comes, it does not only come while closing shotcut it comes sometimes in between of editing videos, sometimes on using other applications, i.e. it never comes in a specific task like after closing this or that it just pops randomly. In your case it is totally different than what I have seen in most cases.

I still don’t understand what is the problem :thinking:.

Does your Mac hangs for sometime (1sec or more), or something else?
