Intel® Iris® Xe Graphics has Memory Leak During the Translation From "gl.textSubImage3D()" JS Function to D3D11 "DeviceContext::UpdateSubresource()"
Content Type: Troubleshooting | Article ID: 000101155 | Last Reviewed: 06/23/2025
The JS function gl.textSubImage3D() is causing a memory leak when it is translated later by all major browsers to DeviceContext::UpdateSubresource() on Windows, as D3D11 is being used by default.
Intel has identified this behavior as known issue. Please check back later for any changes to this situation.
