Hey, I'm using ThorVG 0.15.12 (via vcpkg) with the software render engine.

I have a couple of files that render but don't show anything (all pixels in the buffer are 0 after syncing). I tried some lottie viewers and most of them support the files.

The files play correctly here https://lottiefiles.github.io/lottie-docs/playground/json_editor/ when using the lottie-web SVG renderer and when using the lottie-web Canvas. It does not work when using DotLottie.

For example this file bouncing_ball.json:

• If I "convert" (load and export) the file via lottiefiles, the problem persists (bouncing_ball_lottiefiles.json)
• If I convert via lottielab then lottie-web SVG works and DotLottie works. lottie-web Canvas does not work anymore (bouncing_ball_lottielab.json)

Here are more files with the same problem

lego_loader.json
material_wave_loading.json
R_QPKIVi.json
techno_penguin.json
Twitter Favorite Heart.json
confetti.json
