Hardware acceleration broken in CD 31.0?

Comodo Dragon - CD Bug Reports - CD
#1

Hello,

I noticed that in the most recent update (31.0) scrolling is very… stuttery… and I figured out it was because CD limited the framerate to 60 while it had previously had 120 (because I have a 120Hz monitor)

Using this link in CD 30.0 used to report 120Hz refresh rate when running a 120Hz monitor, now in CD 31.0 it reports 60Hz to 63Hz on my 120Hz monitor, besides that it also says “BROWSER BUG: Chrome VSYNC non-synchronization bug. Restart browser.” I restarted my browser and I still get the same thing.

On the site previously mentioned I also found out about chrome://gpu (or in this case dragon://gpu) which reports the following:

And as we see from the above it claims all things graphics doesn’t have hardware acceleration, it’s unavailable for some reason?

Specific symptoms of the bug and steps you can take to reproduce it (step by step).
The symptoms is a generally slower browser on a 120Hz monitor since the browser will think it should v-sync to 60 instead of 120(?) as well as hardware acceleration not working (?)

Specific steps you have taken to try to resolve it.
Restart my browser, disable all extensions, disable and re-enable hardware acceleration, played around in dragon://flags to see if I could find a setting that fixes it. (haven’t been able to resolve it)

Comodo Dragon Version (Stable/Beta) e.g. Dragon 4.1.1.11 (Beta); e.g. Dragon 4.1.1.12 (Stable)

If you have Google Chrome installed then please mention it’s version and whether the same issue reproduces with it.
Google Chrome Version 31.0.1650.63 m - Issue is NOT present.

Edit: I’d like to point out that this bug makes the browser really horrible to use for me, I think this might have been it for me… waiting so long for an update that would fix the extension updating issue and then this comes and fixes that but makes the overall browsing experience horrible… If I have to wait several weeks again for an update or a fix then I’m probably going to find another browser because this is seriously getting ridiculous.

Hello,

There have been some fixes added to the new build in order to solve and issues with WebGL content being unavailable.
For starters, can you check if hardware acceleration is enabled in Dragon (dragon://settings > Show advanced settigns > Use hardware acceleration when available) ?

Thank you.

#3

Yes it’s enabled. (added a screenshot just cuz)

Edit: Regarding the edit in my first post, don’t get me wrong, I really want to use Comodo Dragon… but there always seems to be some kind of issue that just drags it down for me. :-\

There are some issues with the hardware acceleration on NVidia graphics cards. We will be focusing our efforts on solving this issue.

There seems to be an issue with detecting hardware acceleration on your system. Can you tell us your graphics card model and driver version?

Regards.

Gigabyte GeForce GTX 780 Windforce 3X (GV-N780OC-3GD) with the 332.21 drivers

#6

I’ve done a clean install of Windows and the Nvidia drivers but still the same thing with CD.

#7

Hello,

Would it be possible for you to run your initial tests with a Chrome or Chromium version? Having some comparison results would be useful.

Thank you for your support.

Okay that’s… weird… I checked the dragon://gpu at least 5 times after re-installing windows and every time it said hardware acceleration unavailable… I now installed Google Chrome and on chrome://gpu it said Hardware accelerated on every point… I then went to dragon://gpu in CD again and now all of a sudden it says hardware acceleration available on all points. ??? And the framerate test site shows 120Hz again.
Edit: The test site shows around 60 Hz sometimes and 120Hz sometimes, it sometimes shows 60 Hz and run at 60Hz then suddenly starts to run at 120Hz… it’s really weird, this didn’t happen in CD 30.0 from what I remember.
Edit 2: I just tested with Comodo Dragon 30.0 portable and it always and instantly detects 120Hz. 31.0 seems to only detect it sometimes.

But still scrolling with the Chromium Wheel Smooth Scroller extension feels stuttery/laggy compared to when I had CD 30.0 (Is it possible I could get a link to CD 30.0 portable to test my theory?) But then again it never updated during CD 30.0 because of the bug and hence I was always on 1.3.4 but now when I got CD 31.0 it of course updated to 1.3.6 so it might be an extension issue, either way I’d like to test it with CD 30.0 portable if that is possible.
Edit: I disabled: “GPU compositing on all pages” & “Threaded compositing” and I think scrolling is less stuttery but still a lot of ghosting (when I scroll I see the actual page and then a ghost page behind it, it’s as if the webpage were two pages with a rubber band fixed between them and when you scroll you pull on one and the other is following on the rubber band… If that makes any sense…)
Edit 2: There was a lot of placebo thinking the setting made it better but in reality it made it tiny tiny better at best.
Edit 3: I just tested with Comodo Dragon 30.0 and oh my god it’s so much smoother, I’ll try to record the difference but it might not show since lol youtube is 30 fps, but hey I could give you the raw file, anyway I’ll look into that. Well I ran into the issue that the recording wasn’t able to record the difference because it wouldn’t record a stable 120FPS… well it would record that but the browsers wouldn’t run at a constant speed, they would fluctuate and such.

Below is from Comodo Dragon now

I have downgraded my “fully installed” (not portable) Comodo Dragon to 30.0 and it’s running smooth again, that teaches me to always try new versions of Comodo Dragon as portable first. ^-^‘’ Also, updating extensions in CD 30.0 is now “trivial” for me, you can’t really update them so you need to uninstall and then install them again and then you lose the settings for those extensions, but I just now found out that you could just keep a backup of the settings from the Local Storage folder and copy them back after re-installing the extensions…

Edit: I think it’s worth clarifying some things, I thought these issues were related, but it seems they are not. The three issues in this bug report are:

[ol]- Scrolling is not smooth as it was in CD 30.0

Regarding the first issue: I believe this is a Chromium issue since I installed Chrome and I have the same effect as in CD 31.0 (i.e that it’s not smooth, somewhat stuttering) but in CD 30.0 it’s smooth, which makes me think Google yet again changed something to yet again make the browser s-s-stut-t-ter for me.

Regarding the second issue: I don’t really know about this one, it seems to just have fixed itself somehow, how I do not know…

Regarding the third issue: I haven’t been able to reproduce this with Google Chrome and it doesn’t happen in CD 30.0 so it makes me believe it is a CD specific bug instead of a chromium specific bug.

I’m still having issues with sluggish scrolling in CD 31.1, as if it was cutting out 50% of all the frames when scrolling… you know as if I was scrolling in 30FPS or something.
