Memory Leak during export on Linux

What is your operating system?
Linux Mint
Kernel 6.4

What is your Shotcut version (see Help > About Shotcut)?

Can you repeat the problem? If so, what are the steps?
I try to export 25 minute 4K 60fps video, and after 25% of export it stops.
I see increase in memory usage to 100% (I have 32GB of RAM).
I used HW and SW enabled encoding, see the same problem

That is not a version we ever made and therefore do not support. More than likely whoever made your packages combined a bad version of Shotcut and MLT. Try again with a build from our download page.

I installed it using Discover on my Linux Mint machine. Thank you, I’ll uninstall it and install from

Maybe your MLT package is version 7.16.0, which is known to have bad leakage. Our Shotcut release builds never intentionally used that version.

Thank you. The newest version 23.07.29 doesn’t have any memory leak for me and I’m encoding my video right now
