Intel UHD 630 d3d11 driver viewport bug?

[halx99]

Driver bug?

reproduce step

1. axmol new HelloCpp
2. modify frameSize(1024,768) and designResolutionSize(1920, 1200)
3. change resolutionPolicy to NO_BORDER
4. ensure setStatsDisplay(true)
5. axmol build -p win32
6. ensure HelloCpp.exe runs in Intel UHD 630 graphics, can switch in windows11 display setting
7. run HelloCpp, you can see the FPS label not show completely

A little debugging: this bug may caused by glViewport origin(x, y) < 0, maybe viewport origin < 0 can't works properly on UHD 630 d3d11 driver

workaround solutions

• ANGLE: d3d9 + AX_GLES_PROFILE=200
• ANGLE: GL
• Disable ANGLE by -DAX_USE_COMPAT_GL=OFF
• Use high preformance display device adapter: Nvidia or ATI
• Disable stencil: _director->getRenderer()->setStencilTest(false) if your project not stencil test
