Same trick as in fb: just do a normal GetImage and deal with the planemask on the CPU if you have to. Since the software fallback hit for glamor is pretty brutal, this is a much more impressive win for glamor than it was for fb: 11100.0 87700.0 (7.901) (copy 0xaaaaaaaa) ShmGetImage 10x10 square 9840.0 47800.0 (4.858) (copy 0xaaaaaaaa) ShmGetImage 100x100 square 1550.0 4240.0 (2.735) (copy 0xaaaaaaaa) ShmGetImage 500x500 square 9450.0 78900.0 (8.349) (0xaaaaaaaa) GetImage 10x10 square 6910.0 30900.0 (4.472) (0xaaaaaaaa) GetImage 100x100 square 431.0 2020.0 (4.687) (0xaaaaaaaa) GetImage 500x500 square Measured with Xephyr -glamor on Skylake GT3e.
