Chrome 26 vs Chrome 41 (screen tearing) #975

Open GoogleCodeExporter opened 9 years ago

Please check out this WebGL benchmark:
http://necromanthus.com/Test/html5/test8.html 
Press "F" for full screen.

Tested on a dual-boot computer (Core 2 Duo E6400, Nvidia GTS 450):
1) Windows XP SP3 with Chrome 26
2) Windows 7 SP1 with Chrome 41

1. 59-60 FPS, very smooth motion, no tearing at all
2. 59-60 FPS, very smooth motion, severe tearing (horizontal lines).

Monitor set at 1600x900 and refresh rate at 60Hz.

In my opinion the issue is related to "requestAnimationFrame".
Chrome 26 is in perfect sync (no matter if the monitor refresh rate varies 
around 60)
Chrome 41 is out of sync (it's probably locked to 60).

all the best

You should look into it.
Because it's about D3D9 vs D3D11 (the bug is related to D3D11).
