when I set input and output resolution all the same, 2048x1024, validation error get fixed. But still I cant figure out where is the problem. Which attachment RT size get wrong?

and the output log is below: [2026-01-22 12:42:00] Compiled shader: Hidden/PostProcessing/ExtractUIHint, subShaderLOD:0, pass: <Unnamed Pass 0>, stage: fragment, codeSize: 1059, keywords OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 72 {t:1769056920.688173,tid:0xfd221e,offset:0x4a67d0c} ERR mtlTexColor gfxFormat: 70, size: 1024 x 512 ~ 1024 x 512 OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 73 {t:1769056920.688209,offset:0x4a67d7c} ERR mtlTexPrevColor gfxFormat: 70, size: 1024 x 512 ~ 1024 x 512 OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 74 {t:1769056920.688219,offset:0x4a67dec} ERR mtlTexMotion gfxFormat: 65, size: 1024 x 512 ~ 1024 x 512 OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 75 {t:1769056920.688224,offset:0x4a67e5c} ERR mtlTexDepth gfxFormat: 55, size: 1024 x 512 ~ 1024 x 512 OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 76 {t:1769056920.688230,offset:0x4a67ecc} ERR mtlTexUI gfxFormat: 70, size: 2048 x 1024 ~ 2048 x 1024 OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 77 {t:1769056920.688235,offset:0x4a67f3c} ERR mtlTexOutput gfxFormat: 80, size: 2048 x 1024 ~ 2048 x 1024 OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 78 {t:1769056920.688245,offset:0x4a67f98} ERR m_MTLFXTemporalScaler inputSize: 1024 x 512 outputSize: 2048 x 1024 OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 79 {t:1769056920.688252,offset:0x4a67ff4} ERR m_MTLFXTemporalScaler colorFormat- 70 depthFormat- 55 motionFormat- 65 outputFormat- 80 OSLOG-8E9458FC-7294-45FC-B2B2-10E6E69096A7 7 80 L 7a {t:1769056920.688259,offset:0x4a68064} ERR FrameInterpolator colorFormat- 70 depthFormat- 55 motionFormat- 65 outputFormat- 80 uiFormat- 70 /AppleInternal/Library/BuildRoots/4~CB3qugCnkOnvt3utP5EjRtMy8k8SCYMtZU_Tyn4/Library/Caches/com.apple.xbs/Sources/MetalFX/Framework/MetalFXDebugError.h:29: failed assertion `Color texture width mismatch from descriptor'
