Chrome Version: 72.0.3619.0 (locally built content_shell)
OS: Linux

What steps will reproduce the problem?
(1) ./content_shell --show-fps-counter --force-gpu-mem-available-mb=1 --disable-gpu-rasterization
(2)
(3)

What is the expected result?
The max gpu memory text should be red since it didn't have enough memory for all tiles.
The "GPU Raster" should say "off (device)" in red color.
The memory gradient meter should go from green to red. 

What happens instead?
The texts mentioned above are blue and the gradient goes from green to blue.

I don't know if this has regressed recently, just discovered it by accident.

Note that the issue exists with --force-gpu-rasterization as well, just wanted to point out all places in the HUD that were showing the problem. 

It only happens when Skia is run using BGRA which is the default for non-Android. If I switch to RGBA it works as expected, i.e. by modifying skia/config/SkUserConfig.h and getting rid of this section:
#if !defined(ANDROID)   // On Android, we use the skia default settings.
 #define SK_A32_SHIFT    24
 #define SK_R32_SHIFT    16
 #define SK_G32_SHIFT    8
 #define SK_B32_SHIFT    0
#endif

I found that the issue goes away and works as expected in both rgba and bgra mode if I drop the color swizzling here:
