The only fix may be to use desktop portal for recording. This issue doesn't appear on x11 since these modifiers are not used by xorg server. This issue only appears on some intel iGPUs, such as Intel Iris Xe, see: https://github.com/dec05eba/gpu-screen-recorder-issues/issues/1. -Intel dedicated GPU (intel arc a750) can have a similar issue, but it's not related to compression. In that case the modifier is I915_FORMAT_MOD_4_TILED. + The compression format is described in libdrm/drm_fourcc.h (I915_FORMAT_MOD_Y_TILED_CCS comment). The main surface is plane 0 while plane 1 contains the compression data. + The compression data (plane 1) is 1024x512 pixels and matches the main surface (plane 0) and it's divided into 128Bx32 blocks, + but the data is actually QWORD (bytes) so it's in 64Bx64 tiles (?). Test if p2 state can be worked around by using pure nvenc api and overwriting cuInit/cuCtxCreate* to not do anything. Cuda might be loaded when using nvenc but it might not be used, with certain record options? (such as h264 p5). nvenc uses cuda when using b frames and rgb->yuv conversion, so convert the image ourselves instead.- @@ -148,4 +150,6 @@ Use MapTexture2DINTEL for software encoding on intel.
