| 17:54.58 | TSquare | @AcidWeb ^ |
| 17:55.31 | TSquare | Thanks Simca |
| 17:56.03 | TukuiDevs | <Merathilis> @TSquare, you would make a lot of people happy, if they would be available for the public. ð |
| 17:57.11 | AcidWeb | TSquare: Generally some hidden option that allowed to disable pixel snapping introduced in 8.1 would save many headaches for us. |
| 17:59.21 | TSquare | I'll try and find out about that, or some other way to turn it off. I'm out after tomorrow on vacation, so it may not happen until I get back. |
| 18:04.27 | Alram | going anywhere? |
| 18:05.53 | TSquare | Dice Tower West, it's a board game convention in Las Vegas. |
| 18:06.02 | Alram | neato |
| 18:06.10 | Alram | enjoy |
| 18:06.14 | TSquare | yea, I'm excited. It should be a lot of fun |
| 18:06.30 | Alram | i frequented those kind of conventions when i was younger |
| 18:06.42 | Alram | moreso for the pokeymans though because that was the same convention |
| 18:06.42 | TSquare | me too |
| 18:07.12 | TSquare | I went for the role playing :P (this was in the mid 80's) |
| 18:07.48 | Alram | ah yes the 80s |
| 18:07.55 | Alram | infinitely better because i wasn't born yet |
| 18:08.02 | Alram | and neither was Fisker |
| 18:18.02 | TheDanW | what's the problem(s) you're trying to solve by adjusting pixel snapping globally? |
| 18:19.48 | AcidWeb | Changes implemented in 8.1 made achieving pixel perfection in full UI overhauls... not fun. |
| 18:20.27 | TheDanW | because it clashes with existing addon methods of achieving pixel perfect? |
| 18:22.10 | TukuiDevs | <Merathilis> Yes |
| 18:23.50 | AcidWeb | Breaking old methods is problematic but that is not main problem. |
| 18:24.00 | AcidWeb | After extensive research we not found new ones |
| 18:26.47 | TheDanW | in what way? we can help fix the root problems instead of just disabling it globally |
| 18:27.44 | AcidWeb | We have cases where two people with exactly the same settings and resolutions see different things. |
| 18:28.02 | AcidWeb | I don't have idea what is wrong. But that definitely started with 8.1. |
| 18:28.31 | *** join/#wowuidev stolenlegacy (~stolenleg@unaffiliated/stolenlegacy) |
| 18:29.23 | AcidWeb | We talking about ~1px anomalies I doubt that is visible at all in default ui. |
| 18:30.29 | AcidWeb | Pre 8.1 you could just set scale with high precision and you are done. |
| 18:30.38 | AcidWeb | Now this is some random nightmare. |
| 18:30.47 | TSquare | @Simca - do you have instructions on how to trigger it? |
| 18:31.26 | Simca | should be in that message, but just apply toy, repeatedly shift forms |
| 18:32.05 | TheDanW | AcidWeb: if you can create a minimal repro case then we could try to figure out whats going on |
| 18:34.17 | AcidWeb | I can't replicate that at all. After two days of tweaking i fixed that for myself on 1440p. |
| 18:34.34 | AcidWeb | In my case setting ui scale with 5 digit precision works. |
| 18:34.53 | AcidWeb | But we have multiple 1440p users where that don't work properly. |
| 18:36.27 | AcidWeb | Same math in same environment but on different computer fails.. |
| 18:36.35 | AcidWeb | This is strange AF. |
| 18:38.25 | AcidWeb | I also seen some people where PixelUtil.GetNearestPixelSize() returned different values for same input. |
| 18:38.41 | AcidWeb | It is like float operations fail somewhere on client level. |
| 18:39.50 | TheDanW | it's possible there's some rounding error, but we'd need a bit more to go on :/ |
| 18:43.16 | AcidWeb | Even if you bypass PixelUtil completely, don't touch uiscale cvar and set everything manually you can get two different results with the same settings on two different computers. |
| 18:43.46 | AcidWeb | I always thought that was fault of pixel snapping implemented in 8.1. |
| 18:45.06 | AcidWeb | As I said I'm talking about ~1px anomalies I highly dobut that users of default ui noticed that. |
| 18:45.32 | AcidWeb | But if you trying to make your UI Sexy⢠- you are screwed after 8.1. |
| 18:45.50 | AcidWeb | And probably need to find a scale that works for you as pixel perfect. |
| 18:46.19 | AcidWeb | And that value should be static per resolution - and definitely it is not. |
| 18:48.32 | AcidWeb | I personally use 0.53333 for 1440p but I know that some other 1440p users need to find personal sweet spot between 0.52 and 0.54. |
| 18:53.41 | znf | I'm still trying to figure out why people have issues with the UI Scale |
| 18:53.50 | znf | I'm on 1440p, I just turned it off and my fonts are properly scaled |
| 18:54.07 | AcidWeb | Good for you. |
| 18:54.26 | AcidWeb | But tons of people want to achieve pixel perfect UI. |
| 18:54.53 | znf | and I do have it... otherwise my pixel fonts would render horribly |
| 18:55.08 | AcidWeb | Or want see nice 1px borders even if they don't know what pixel perfection is ð |
| 18:55.49 | znf | I'm not saying your issue is not valid, it's just that from experience, when you mess with the UI Scale, stuff breaks *shrug* |
| 18:57.20 | AcidWeb | In 8.1 that is definitely a correct statement. |
| 19:17.37 | Gnarfoz | when did turning off uiscale stop being the solution to this? |
| 19:18.46 | znf | dunno, that's what I'm trying to figure out |
| 19:18.53 | Gnarfoz | (also, wasn't there a lower bound to uiscale values that actually do anything? 0.64 or something?) |

| 19:25.35 | Stanzilla_ | I guess the main problem is that there are no guidelines or developer comments on how the new pixel grid stuff shsould be used by addon authors, so everyone does his own thing and disables it here and there and the end result is an even bigger mess than before |
| 19:34.25 | *** join/#wowuidev kd3 (~quassel@unaffiliated/kd3) |
| 19:40.04 | AcidWeb | Gnarfoz: Yes official UI cap that on 0.64. |
| 19:40.21 | Gnarfoz | nah, there's a lower bound for even setcvar |
| 19:40.29 | Gnarfoz | not sure what it is, though |
| 19:41.11 | AcidWeb | And disabling uiscale definitely don't give same result as setting pixel perfect one. |
| 19:43.03 | AcidWeb | Your UI don't need to be pixel perfect to pixel fonts look correctly. |
| 19:43.23 | AcidWeb | There are multiple scales where they are displayed correctly. |
| 19:49.12 | Stanzilla_ | for example in WeakAuras we had to SetSnapToPixelGrid(false) SetTexelSnappingBias(0) to make things work correctly after 8.1 which seems counter productive |

| 20:28.43 | TheDanW | SetTexelSnappingBias > 0 implies SetSnapToPixelGrid true |
| 20:29.11 | TheDanW | if they're 0 and false then its exactly the same as pre8.1 |
| 20:29.46 | TheDanW | just because pixel snapping is on doesn't mean your corners will line up, the two pieces anchored to each other can round opposite directions |
| 20:29.56 | TheDanW | depending on ui scale, resolution and the entire anchor chain |
| 20:30.15 | AcidWeb | OK. Then problem is caused by something else then. |
| 20:30.16 | TheDanW | and any time one of those changes the final positions need to be readjusted |
| 20:30.38 | TheDanW | manually through like SetPoint or SetSize |
| 20:30.44 | TheDanW | or the pixel util functions |
| 20:31.43 | AcidWeb | Yeah question is - why people with the same scale and same resolution require different readjustment for object in the same place. |
| 20:32.01 | TheDanW | i forget if there's any exposed documentation, but texel snapping bias can essentially be though of how aggressively we filter from bilinear to nearest neighbor |
| 20:32.08 | TheDanW | thought* |
| 20:33.42 | TheDanW | its likely rounding error, perhaps with the order of anchor resolution, if the results of GetRect are identical it could also be gpu/driver related as ultimately the hardware is going to be choosing a pixel |
| 20:34.07 | AcidWeb | Well that was not an issue before 8.1. |
| 20:35.19 | AcidWeb | And over entire life cycle of 8.1 we not found any workaround that works every time. |

| 20:36.56 | Simca | reminds me when Blizz had a rounding error in the pet battle system with stat calculations (FP accuracy issues between Lua and C doing things slightly differently I think) |
| 20:38.16 | Simca | i finally decided to account for it in my addon, to inflate all the numbers to remove the decimals, which emulated however blizz was rounding since we started getting the same result finally. years and years later, my addon is getting wrong results at level 1 pets sometimes - i think the rounding error was eventually resolved years down the line |
| 20:38.29 | Simca | and i need to go back to the old way i was doing it |
| 20:38.37 | TheDanW | for people that see it correctly, what is the return values from GetRect vs those that see it incorrectly? |
| 20:38.44 | TheDanW | assuming same resolution and ui scale |
