Canvas in Google Chrome 61.0.3163.79 are too slow on Linux
I found workaround. After upgrade Chrome to 61 version I faced same experience with you.
Try adjust following chrome flag to Disabled.
chrome://flags/#enable-color-correct-rendering
I expect Default flag have different means with before 61 version.Below the result is in my case on attached url from you.
Default - 5 fps
Disabled - 35 fps
I wish this help you.
The enable-color-correct-rendering flag does not exist after upgrade to Chromium 62.
Fortunately the slowness disappeared after setting flagchrome://flags/#force-color-profile to sRGB as mentioned on google forums
Tested on Chromium 62.0.3202.75, 64-bit, Linux
The solution for me was disabling Use hardware acceleration when available
setting:
Chrome menu > Settings > Show advanced settings > Scroll down to "System" > Uncheck "Use hardware acceleration when available"
I had the same problem with Version 69.0.3497.81 (Official Build) (64-bit).
I tried all already proposed combinations of enabling/disabling features from chrome://flags. But they didn't work for me.
