x11 gives errors after switching to lavapipe from turnip

i'm trying to switch to lavapipe from turnip, i compiled it from latest mesa with flags -Dvulkan-drivers=swrast -Dgallium-drivers=[] -Dcpp_rtti=false and then made a file called lvp_icd.aarch64.json in usr/share/vulkan/icd.d with those contents

{
    "ICD": {
        "api_version": "1.3.295",
        "library_path": "/data/data/com.termux/files/home/mesa/build/src/gallium/targets/lavapipe/libvulkan_lvp.so"
    },
    "file_format_version": "1.0.0"
}

{
    "ICD": {
        "api_version": "1.3.295",
        "library_path": "/data/data/com.termux/files/home/mesa/build/src/gallium/targets/lavapipe/libvulkan_lvp.so"
    },
    "file_format_version": "1.0.0"
}

but then when i try to run vkcube the screen in termux x11 is black, some other programs fail with

X Error of failed request:  BadMatch (invalid parameter attributes)
Major opcode of failed request:  147 ()
Minor opcode of failed request:  4
