英文:
Cannot disable Hardware acceleration using Selenium in c#
问题
我正在使用C#中的Selenium库来打开和控制Chrome。当Chrome打开后（我正在测试回放事件），我会对显示器进行截屏并处理它们以确定某个事件发生的时间。问题在于，由于硬件加速（我认为这是问题的原因），截屏返回为空（黑色）。我如何强制Selenium代码中打开的Chrome禁用硬件加速？
我尝试过在Chrome本身中禁用硬件加速（在设置和chrome://flags中），但Selenium仍然以硬件加速打开Chrome。我尝试强制Selenium使用以下方式打开Chrome以禁用硬件加速：
new DriverManager().SetUpDriver(new ChromeConfig());
var options = new ChromeOptions();
options.AddArgument("--disable-gpu");
driver = new ChromeDriver(options);
但是代码似乎忽略了这个参数，仍然以启用加速的方式启动。
有人可以帮助我解决这个问题吗？我更希望不改变截屏方式，但如果有必要，我也愿意考虑。谢谢。
注意1： 我愿意接受非编程解决方案。如果有一种方法可以指导我的用户自行关闭硬件加速，我会考虑它是有效的（即使不是首选）解决方案。
注意2： 如果您认为这有助于解决问题，我甚至愿意切换到其他浏览器。
更新： 我尝试了类似的解决方案用于Firefox和Edge，但似乎也不能解决这个问题（至少在我通过Selenium启动浏览器后检查设置时，硬件加速仍然显示为已启用）。我还尝试在user-data / Preferences / Settings中添加 "hardware_acceleration": false，但结果似乎是相同的。
英文:
I am using Selenium library in c# to open and control Chrome. When the chrome is opened (I am testing playback events), I take screenshots of the monitor and process them to determine when certain event occurred. The problem is that due to hardware-acceleration (i suppose that is the problem), the printscreens come back empty (black). How can I force the chrome opened by Selenium in my code to have hardware-acceleration disabled?
I have tried disabling the hardware-acceleration in chrome itself (in settings and in chrome://flags), but Selenium opens chrome with HW-acceleration anyway. I have tried to force Selenium to open chrome with HW-acceleration disabled like this:
new DriverManager().SetUpDriver(new ChromeConfig());
var options = new ChromeOptions();
options.AddArgument("--disable-gpu");
driver = new ChromeDriver(options);
but the code just seems to ignore the argument and starts with acceleration enabled anyway.
Can anyone help me solve this problem? I would prefer not to change the way I take screenshots, but if that is necessary, that would be helpful as well. Thank you.
Note 1: I am open to solutions that are not programatical. If there is a way to instruct my users to switch of hardware acceleration themselves, I would consider it to be a valid (even if not preferred) solution.
Note 2: I am even willing to switch to a different browser, if you think that would help.
Update: I have tried similar solutions for firefox and edge and those does not seem to resolve the issue either (at least when I check settings after launching the browser via Selenium, hardware acceleration is shown as enabled).
I have also tried adding ""hardware_acceleration": false," to user-data / Preferences / Settings, but the result seems to be the same.

"Try this two arguments:
options.AddArgument("disable-gpu");
options.AddArgument("disable-software-rasterizer");"
英文:
Try this two arguments:
options.AddArgument("disable-gpu");
options.AddArgument("disable-software-rasterizer");
