Turned out to be improper handling of non-uniform texture array indices between fragments in the same wave
Oh it's per-wave, that makes so much sense
It's definitely the left side of the first texture: the white parts at the top of the artifact line up with the crossbar of the T at the start of "This is a very long text."
Oh I didn't realize you had to wrap the relevant index use in that
Once I do the issue disappears, thank you!
Do you mean enabling GL_EXT_nonuniform_qualifier? I don't have it enabled but I just tested and doing so has no effect on the artifact
It does, it flickers
@lisyarus.bsky.social suggested a mipmapping issue over on Mastodon and it seems like that might be it, forcing a read from both tiles before choosing which value to use makes the artifact vanish
Texture looks 100% fine in RenderDoc
A text rendering test with "This is a very long" repeated twice.
Doesn't occur when I read from the same image for both regions either
A large letter g with a glitched crack through it.
A pair of rectangles side-by-side in UV debug colors.
Does anyone recognize this artifact? I'm storing the texture in multiple images to avoid exceeding max image dimensions and I'm getting this weird glitch at the tile boundaries
Even stranger, it isn't reflected in the UVs (second picture) and the sampler is set to nearest + clamp-to-edge
Wrote up an article about how I ended up tackling this problem from January (spoiler: I gave up on barriers), might be useful to somebody out there learning Vulkan for compute

Surprised by how much better Marathon feels in full release vs. the playtest
Unsure if it's just placebo but I'm seeing much more PvP, more loot variety and more cooperation in filled squads (though misaligned objectives for randomly filled players is still A Problem)
All estimates I've seen for the fraction of Destiny 2 players that ever saw a raid are <25%
No doubt that's being dragged down by a lot of free-to-play accounts that never made it out of the tutorial, but it still suggests Marathon's will be niche content
As the other comment said, most languages that do this (e.g. Python, Crystal) use a "range" type which represents a span of numbers as a start value, an end value and possibly a step value
No array containing all the values is ever allocated

Long time no see but I've finally written a new article!
This time I'm laying out my thoughts about the new Marathon playtest and its struggles with motivating and incentivizing players

A cube rounded on four edges in a 3D editor.
Adding more primitives to the editor game masters will use, this time it's the "rounded rectangle prism"
Reminiscent of how most Destiny mechanics are mediated via shooting things and acquiring buffs because the gameplay systems can't really do anything else
Marathon thoughts:
Art & soundscape are top-notch, gameplay feels really good but player motivation is iffy?
"Break glass across Tau Ceti" is not an objective I get excited about, it feels like a daily, and I can feel the writing straining to justify objectives the gameplay can support
No, it's the same category of application as Steam ROM Manager (I'm sure there are others)
It adds shortcuts to non-Steam applications (e.g. emulated games, games from other launchers) to Steam so you can launch them via Steam
For example in the images above I have added a shortcut to Ubisoft Connect, another game launcher, with artwork to make it fit seamlessly into my Steam library
I believe you can use Heroic Games Launcher to access most EGS titles on a Steam Deck (not Fortnite though, the anti-cheat disallows Linux)

If you like adding non-Steam games to your Steam Deck I have something for you! An update to my tool for batch configuration of non-Steam games from a config directory you can back up
It now supports both customizing images on official Steam games and setting "wide" images
Built a toy example to make sure my understanding of rollback logic is sound
You can see how the client initially goes past the blue barrier, which only exists on the server, before rollback kicks in and corrects the position
Yup! I made it because I needed a language that was "suspendable to text", you can save the scripting context in human-readable form at any time and resume executing later
Horrible frame rate is due to the network problem this setup is intended to debug, please ignore
It's pretty cool to be able to script objects in my game with my own text editor and my own language, from inside the game itself
I've updated the documentation to make it easier to understand, updated the CMake & Qt versions to modern standards, fixed some crashes in edge cases and added a second header-only plugin so you can now emit dumps from C projects!
A chain of blocks filled with numbers representing world states, colored green or red depending on whether or not they represent a correction of the client state due to rollback.
Something for anyone working on multiplayer networking for their game: while trying to fix my own game's netcode I updated my tool Rollback Diagnostic
The tool lets you create dumps from your game of multi-timeline world state and use a graphical viewer to explore them
