"The Art and Secrets of #Karambola" - a digital 92-page #artbook heavily illustrated with yet unpublished sketches, drawings, paintings and locations from the game - is now out!

Agata (@holypangolin) reveals her thoughts on the curious fruity characters’ personalities and backstories, as well as some difficult decisions she had to make during the design process.

The recording of my #FOSDEM talk - a dive into a bug in USB 2.0 and the problem of spontaneous modem resets that used to be experienced on the #Librem5 is now available to watch: https://fosdem.org/2024/schedule/event/fosdem-2024-3200-universal-serial-bug-a-tale-of-spontaneous-modem-resets/ #linuxmobile #mobilelinux #usb #fosdem24 #fosdem2024 #fossonmobile #mobile #linux

The newest game I've been working on, ODGŁOS, is finally available to play! A cute owl, the history of electronic music, shapeshifting snakes and intergalactic journeys inside the Polish Radio Experimental Studio - all in a stop-motion interactive story :) You'll need a browser, headphones and 30 minutes to spare. Have fun!

#Introduction time!
My name is dos; some call me Sebastian. I made dozens of small silly video #games and some slightly less small ones too. I'm one half of @holypangolin studio. Sometimes I pretend to be a musician, but don't get fooled. I'm also a living encyclopedia on a Polish rock band "Perfect". Trams are cooler than trains. The more caramel, the better. I've been using GNU/#Linux on #mobile phones for ages, which led me to work with @purism on the Librem 5. btw I use Arch, but I ❤️ Debian!

Protip: GTK can do hardware video acceleration using V4L2 on e.g. #Librem5, but only if you let it.

Adding "--device=all" to overrides lets it be used in #Flatpak apps that don't specify it in their permissions already, such as #Tuba.

If you happen to maintain a distro that runs on the #Librem5, then please be aware that all the known issues resulting in the modem dropping out from the USB bus have been resolved *years ago* already. This shouldn't happen even with runtime power management enabled if configured properly.

If you still see that happening on your distro, feel free to hit me up on Matrix and we'll work together to have your distro set up well.

The #Librem5 has properly detected chargers using BC1.2, Type-C and PD signaling for years now, but it struggled with sources that couldn't actually provide the advertised current (which could happen with buggy chargers/docks, broken or poorly made cables etc.). It would attempt to draw power, drop below voltage threshold, disconnect, and then do it all again once the voltage went back up to a good level in an endless loop. Good news: this behavior is about to be gone 😁 #mobilelinux #linuxmobile

It's nothing new and has even been proposed for upstreaming years ago, but I wasn't aware until now. Apparently it broke some iMX7 platforms, but could still be something worth having downstream.

NXP has published their 6.18-based kernel tree and while browsing it I have noticed that they apparently found a way to support custom horizontal strides with mxsfb (by using some undocumented leftover IP for EPDC panels that imx8mq doesn't support). This may be interesting as it potentially opens a way to use linear PE in #etnaviv with the #Librem5's internal screen, so the GPU could render directly to the scanout surface without having to resolve its tiled buffer to linear afterwards. #imx8mq

Despite of its enormous codebase it wasn't that hard to look around and find relevant stuff - the GTK layer is fairly thin. The hardest part was to compile it, but running distcc on a Steam Deck sped it up well 😄

We still need to:
- emit pointercancel when the browser takes the touch gesture over
- not change scrolling targets during scrolling just because a new one "flew" onto the cursor/finger
- have some thresholds to differentiate between vertical and horizontal scrolling

All my #WebKit merge requests have been merged. Now #WebKitGTK supports touch PointerEvent API, touch point coordinates are fractional, synthesized mouse events are unbroken and both WebKitGTK and WPE WebKit handle pointer capture and release according to the spec. This should considerably improve compatibility of #Epiphany (#GNOME Web) with touch interfaces.

There are still some more things to fix in there, maybe someone in #mobilelinux #linuxmobile community would like to give it a try?

It's funny how this phone keeps feeling faster as it gets older.

Looks like GTK is starting to get its renderer inefficiencies sorted out, as updating Flatpak runtimes has made Tuba smoother than ever 😄 #librem5
