Opera 12 alpha (1105) with webgl and Hardware acceleration

The last months Opera 12 snapshots have received two major updates of its JavaScript engine, Carakan, which make it more memory efficient and fully ECMAScript 5.1 compliant. Last week the new HTML 5 parser Ragnarök was added. Today Opera 12 alpha introduces another major technological milestone: full hardware acceleration with WebGL.

(...)
Currently hardware acceleration is in an alpha stage and only uses an OpenGL backend. We would like to get your feedback about how well it works for you. Opera 12 alpha works best with modern graphics cards and up to date drivers. In future snapshot we'll add support for DirectX and more graphics cards. Be aware that testing Opera 12 alpha can trigger bugs in your graphics card and in worst case blue screen your computer.

really cool but still has problem with persian (farsi) language, i am tired of reporting bugs, no body answers me and fix problems:(
first for css letter-spacing bug for farsli languages i reported DSK-327459, and this bug is and 4 or 5 years old as i know, http://jsfiddle.net/eTvVu/
i even made an extension to remove any letter-spacing in page (https://addons.opera.com/addons/extensions/details/letter-spacing-fix/) but it's not the solution!

and then reported DSK-346172 , the problem with farsi language in css3 transform scale , you can see in this url on hover the text became unreadable http://www.h4ir.com/page.php?page=ads

sorry for my bad english...

I found these bugs in this release
1. Show images- cached images buttin problem
2. improper minimize & maximize

UJS Manager not work.

I foun a blur effect problem with the graphic.

http://forum.de.selfhtml.org/
stuill hangs my whole system for 4-6 sec. every 10-15 sec.
same for some wikipedia pages !

OMG WTF is there?

Are they going to dump old style skins?

Ok, its good but as expected its quite twitchy. Especially on experiments its unbearably laggy.

I used GPU-Z to test,
GPU and Memory Controller Load are okay, but the Memory Used seems a bit too high around 360MB for me, going up to 480MB on certain listed experiments like Emberwind and MS IE Fish Tank, both of which didn't seem to work properly for me at least anyway.

Youtube seems to be getting weired on me after this build, [this is happening occasionally i might add]
I have progress-bar setup to popup at the bottom when page loads, on Youtube videos it pops up, stays there while displaying all stuff that it usually does.

Now, whats happening is while in this state i can't make text selection on that Youtube page, i need to "press the X" on the address bar or use mouse gesture to stop loading page, then i can make text selection.

Also why does Youtube's "Show video info" when right clicking a video show "software video rendering" still.

Lastly why isn't this site working, http://inventfootball.com/ ? (didn't work in the last build as well.)

Opera 12 alpha (1105), Win 7 64-bit, Nvidia 9800 GTX, ForceWare 280.26

Disable hardware acceleration to fix this.

Seems ok here.

No, Opera Skins will remain unchanged.

I try to execute Opera-Next 12 Alpha (1105) on OpenSUSE 11.4 64bits with Nvidia Quadro NVS 140M and Nvidia-driver: NVIDIA v275.21 (latest in Nvidia-repository), but Opera crash instantly. If i execute "opera-next -nohwaccel" then Opera start as normal.
I've sent report to Opera with Crash-log.

Advice!

...cut...

i get display driver crashing and then it doesn't load at all

Radeon HD 4850x2 on windows 7 x64

Just had this out of nowhere, had Opera runing for 4+ hours almost with no issues, then suddenly Kabooom.
[It happened while i opened filehippo and kickass torrents site , but i doubt they seem to be issue as it didn't happen once Opera restarted and neither can i replicate it again now]


These pop-ups just kept coming, had to force shut.

Setup:
Opera 12 alpha (1105), Win 7 64-bit, ForceWare 280.26
Vega backend OpenGL
GL_RENDERER GeForce 9800 GTX/9800 GTX+/PCI/SSE2

That's definitely a problem with HW/acc (it's obviously some triangulation issue).

I'd suggest you update your graphics card's drivers.

I noticed this as well with small font sizes.

The small white text on the Sky news website is a good example of this blurring / doubling effect.

Have gone back to good old software rendering for now, will try hardware rendering again in a later build.

Ok, I disabled hardawe acceleration and now I haven't the blur effect. Thanks! But I'd prefer to have enabled the Hardware acceleracion and have not the blur effect!

Then open "Manage 3D settings" in the NVidia Control Panel, make a profile for Opera.exe and disable all filtering/AA related settings in there. Maybe that would work.

Personally, the WebGL support is enough for me, no need for fancy UI rendering...

The oddest problem I've come across is that in this release, my mouse is very slow but only in Opera! If I bring up another window on top of Opera, or minimize Opera, the mouse speed/acceleration returns to normal.

I fooled around with the Mouse Properties option in WinXP's control panel and finally found a solution: uncheck "disable mouse acceleration in games".

Now why my computer thinks Opera 12a is a game? I have no idea!

Hardware acceleration is disabled; my video card is ancient.

Opera 12 uses up to 60 % (!) auf CPU on my four year old MacBook Pro when I run Spiegel online without blocking the flash ad.

Having many problems with email lately (last few builds):

In the mail panel, it won't let me unselect (deslect?) email accounts to show.
Everytime I restart Opera it looses all my labels.
mailto: doesn't work

No problems here. Have you tried with a clean install?

Spiegel use css "overflow: hidden;" maybe this is why CPU usage is high.

See bel0w on yours?

User JavaScript stopped working when upgraded a portable Opera from 11.52 to 12 alpha (1105). Tried "User JavaScript File=profile\styles\userjs\" and explicit full path. No dice.

Any idea? Shouldn't this be automatically controlled/fixed by now since the Opera installer supports USB/portable installations? Besides, it's getting annoying have to edit operaprefs.ini and change paths to {SmallPreferences} or {Resources} manually after a clean setup.

very crashed version, many pages only black

Added different search engines to address bar (Duck Duck Go and SmartPage), but they don't work. They appear properly, but they don't actually do anything.
