2287 - [PP] Mac transparency problem: demo #10

Status: VERIFIED FIXED

(Core Graveyard :: GFX, defect, P1)

Description

[phillip]

build: 99010812 on RedHat 5.2 and MacOS 8.5
Mac and linux both have a problem with rendering demo #10.

MAC: the animated gear background appears fine. so does the <HR>. but the three
transluscent gifs and the enlarged gear gif are painted as white squares (with
correct dimensions).

LINUX: the background paints but does not animate. the <HR> appears fine. the
four animated gifs in the foreground do not even appear as white boxes. and
Seamonkey keeps the cpu spinning like a top, repainting very slowly and pushing
the gears foreward at about 1 frame every 7 seconds.

need blender implementation for each platform to fix this.

Comment 2

[stuartp]

the animation problems should be fixed now under linux.  isn't blender
implimented in the image library and not natively?

Comment 3

[phillip]

ok, i'm using build 99020213 (Feb 2) on linux. ( mac windows, same day, work
fine)

On linux (on my PII 266): The animation is marginally faster now, i admit, but
it's nowhere close to the 32bit windows build. also, it is still slower than
the same animated gif in "demo #1"

so here's what's left for parity:

1. opacity (alphablending) of images on linux and mac
2. background image loading time on linux

are these issues handled by the os or by seamonkey/gecko?

Putting [Perf] in the Status Whiteboard since we have some performance problems
here also.

Comment 5

[leger]

Inserting Milestone info.

Comment 6

[leger]

Setting all current Open/Normal to M4.

Comment 7

[rubydoo123]

setting Eli as QA assigned to

Comment 8

[stuartp]

blender is XP and works under unix.

Comment 9

[michaelp]

blending is now xp. any problems that remain should be re-written up as either
mac specific (since that is the only platform for which
nsIDrawingSurface::Lock() has questionable functionality), and assigned to
patrick beard or for all platforms.

Using 4.9.99 AM build, Mac and Linux only display the gear background and the HR;
none of the additional images display at all.

Michael, per your 4.7.99, would you like me to break this into a separate bug...?

thanks!

Comment 11

[ramiro]

elig: yes, please break this up into 2 bugs.  one for the mac and one for linux.

assign the linux one to me and the mac stuff as michael describes above. thanks.

Comment 12

[chris hofmann]

to I'll move this one to beard.
Eli, can you open one and assign to ramiro for linux?
moving to m5

Comment 13

[chris hofmann]

to I'll move this one to beard.
Eli, can you open one and assign to ramiro for linux?
moving to m5.

Comment 14

[Eli Goldberg]

Sure. I'll split out the Unix bug.

I'd rather close this bug out and write up new ones, since the behavior has
changed quite a bit over the past three months, and this one is becoming
increasing hard to follow as a result.

(If anyone objects to this, please let me know ASAP, or it may be too late. ;)

Thanks.

[Unix issue broken into 5053, assigned to ramiro.]

Comment 16

[Eli Goldberg]

[Also, Mr. Beard, the current Mac behavior on the 4.9.99 M4 build is equivalent
to the behavior in 5053 --- except that the Mac:

	a. doesn't have the opaque eyeballs
	b. doesn't have the flashing chrome.
	c. totally horks in a multiple nasty ways if you resize it a few times.
(doesn't fill expanded space with background, window contents go white, sometimes
crashes, etc. Can write up as separate bug report.)

*** Bug 3099 has been marked as a duplicate of this bug. ***

Comment 18

[Eli Goldberg]

[I'm going to break this out into two separate bugs, per bug #1307.]

Comment 19

[Eli Goldberg]

Okay. This bug was branching out into too many issues, and most of the issues
Phillip raised has been fixed.

I've now broken the Mac issue into bug #5081, with a crashing use case scenario.
(As noted before, the Linux stuff is now in bug #5053.)

So, I'm marking this bug as Verified/Fixed. Anyone who sees something that I'm
not seeing, please re-open this with your comments.

(Phillip, are there still performance problems? I'm not seeing them, but I don't
have a visceral gestalt for the feel of the Linux platform, and the performance
always seems slow to me no matter what app I'm using. ;)

Comment 20

[phillip]

for the record, the performance is many orders of magnitude better on linux.
