LTX Video Generation Outputs Blocky Mosaics on AMD GPUs
uebersoldat · reddit · 2026-08-09
A Reddit user reported a severe issue when running ComfyUI with ZLuda on an AMD 6600XT 8GB GPU to generate videos using the LTX 2.3 22b distilled model. Despite strictly following a tutorial's settings, the resulting 480p video quality is extremely poor, resembling a low-bitrate mosaic clip from the 1998 dial-up era, which is far from the clear results demonstrated in the guide.
