Just write another test http://jsfiddle.net/gv7spbLc/
The expected result is moving line without trailing.
If the result is incorrect, change the flag closePath to 'always' or getContext2d to 'always' to see if the issue is solved or not.

Thanks for looking into it. This test also works fine for me, but still no luck with the charts. Wish I could be more helpful than that!

The test script also works fine for me - setting skip & once.
Seems like the coordinates for clearing pattern are calculated wrong on some systems.
Btw, I have two other PCs, also with win 8.1 and the current Chrome version and the charts work fine on them.
Weird Undecided

Yeah, when I disable hardware acceleration the problem is gone. That's probably no fun to debug

No issues.

In the past testing, I met very similar issue which have trailing on a mobile device with hardware accelerate, but the trailing will be disappeared in seconds instead of always shows.
And if the testing code works well, the site should be work well too. That's really weird, I have no idea how it happens, have to rewrite the code slowly and test often to find the cause.

Does it happen today or from hardware upgraded?

noticed some time after win8.1 install + hardware upgrade... not really sure if that triggered it, but my guess is that it did.

And is there any error message in Chrome Console? Press 'Control-Shift-j' to open the console and then press F5 to refresh the page.

No errors... well... only... *cough*

Looks like there is an area on the bottom left that is cleared instead of the main frame. This area is always black, except of the RSI graph that seems to be rendered afterwards.

Yep, the MACD lines are stable as well:

Something funky going on here:

Using the newest Chrome version

https://bitcoinwisdom.com/markets/poloniex/drkbtc

it seems to not refresh/clear the drawing surface as often as it should, because sometimes it gets re-drawn correct after a few seconds.

Am I the only one that experiences rendering issues? chrome (38.0.2125.104 m) win8.1

This has been going on for a while now. It may have started after I installed win8.1, but I'm not sure...

Doesn't happen in Firefox, but the chart is slow as hell there...

I've created a small script to test the compatible. http://jsfiddle.net/x1ny28bh/1/
Open the link and click 'ClearByAssign' or 'ClearByClearRect' in right-bottom, to check if the rectangle cleared or not.

This works in chrome. I believe it may be a combo of chrome and win 8.1 as it is a mess for me on my 8.1 pc, but on my win 7 laptop and newest chrome, there is no issue.

Also, it seems there is a trailing line of flat candles to the far right of the graph

It looks like the canvas is not cleared. The cursor cross line uses same function, but according to screenshot, the cursor line is cleared correctly. If both function works in the test script above, it would be really weird, still have no solution to solve it.

Have the exact same problem since updating Chrome a couple weeks ago. Updated it again today with no fix, currently running version 38.0.2125.111 m, on win7 64bit. For the first time in about forever I actually have IE open on my computer because of this, sad day Sad

.

fwiw that test script works fine for me.

Now I've changed the clear canvas function. Hope it could work.

Not for me Undecided

Still the same Sad

I don't have the problem at work, also win 8.1 + latest chrome (beta actually). Switched to chrome beta at home as well, but it had no effect.

FWIW: with my win8.1 install (when the problem started) also came new hardware. I'm now using an Intel CPU (i7 4790). VGA is the same (AMD R290X).

Both buttons clear the canvas.
