Double-buffering bug RADEON drivers on Windows 7 Classic theme or Windows Basic theme

01/03/2019

Double-buffering bug RADEON drivers on Windows 7
Classic theme or Windows Basic theme (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 v19.1.1 (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 in 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)

Video demonstration

For fix this 2D performance bug - Classic theme for Windows 7 with GPU acceleration "Classic AE mod 2019_5" (April 12, 2019)

Install:
1) Install "UniversalThemePatcher" (Recommended) or "UxStyle" for your Windows 7 OS (32- or 64-bit). If "UniversalThemePatcher" or "UxStyle" is already installed - then this step is skipped. This patch allows you to add third-party themes to your system.
2) Unpack the theme "Classic AE mod 2019_5" in the path c:\WINDOWS\Resources\Themes\

I'm on Windows 8.1 with dwm disabled and classic theme (latest Radeon drivers). Using the WS_EX_COMPOSITED - ON executable reduces the 2DTest draw time from 18ms to 1-3ms. However, I couldn't seem to get the provided theme to work probably due to being on 8.1 (I patched the theme files). In what scenarios would this performance difference be relevant? 2D Desktop applications only? I'm not sure I quite understand what WS_EX_COMPOSITED does, I thought double-buffering would typically add latency not reduce it? Any workarounds for 8.1 would be great (if possible).

Прилично времени прошло на обкатку Classic AE mod 2019_6. По сути, баг с белыми надписями на некоторых кнопках, является единственной проблеммой данной темы. Встречается очень редко, максимум в 5% кнопок, например в Мозилле (см. скриншот). В остальных 95% - надписи выглядят правильно.

В новых версиях Мозиллы, этот диалог переделали - он выглядит иначе и проблема самоустранилась. Но любители классического оформления, зачастую пользуются устаревшими версиями программ, поэтому если кто-то знает как решить баг с белым текстом - то подскажите.
