@kennedyreisz @yuqiang-yuan check out #281 to see if the fix apply to you as well.

@GuilhermeFaga I tried the new 1.3.0 version of AppImage format, still green screen. Thanks

[siddharthvaddem]

can anyone confirm if #281 solves the issue?

[GuilhermeFaga]

@yuqiang-yuan build from my fork to test it.

Issue seems resolved for me on Ubuntu 25.04.

I'm also still seeing the green export, CachyOS/Arch/Wayland/KDE. I'm running 1.3.0. Audio seems to be exporting fine, it's just the video that's solid green.

Super cool tool, looks like it has a ton of promise!

Edit:
I submitted a PR to solve this on CachyOS/Arch, #330

@GuilhermeFaga I've run the application from your fork, and the exported video is ok. thanks. Ubuntu 26.04 Beta, Wayland.
