Indeed, the buffer index is the issue, but I did not check if the ref frames ts are stable. I'll do some tests with it and keep the ref frames in stable output mode if they are stable. > > + if (!stable_output) { > > + visl_get_ref_frames(ctx, buf, TPG_STR_BUF_SZ, run); > > > > - while ((line_str = strsep(&tmp, "\n")) && strlen(line_str)) { > > - tpg_gen_text(&ctx->tpg, basep, line++ * line_height, 16, line_str);
