Double-buffering bug RADEON drivers on Windows 7 Classic theme or Windows Basic theme (any no AERO themes)

This bug all new AMD cards 2014-2019 years:
  • Radeon HD 7XXX;
  • Radeon R5, R7, R9 series;
  • Radeon RX 400, RX 500 series
with Radeon Driver - from Catalyst v15.7 to Radeon Adrenalin v19.3.1 (all versions)

NVidia and Intel video cards there are no problems!
Unfortunately, this problem is present on AMD drivers only.

Using "double-buffering patch" increase RADEON driver performance up 10-30 times!
Demonstration on the foobar2000 spectrum with FPS measurement using simpleGLUT.

No patch (WS_EX_COMPOSITED = OFF)
FPS = 25-60 (very big lags)

Used "double-buffering patch" (WS_EX_COMPOSITED = ON)
FPS = 850-920 (no lags)
