The jokes write themselves!

Enabling FAT LTO reduces the final binary size but it isn't a permanent fix.

[actionfromafar → Flex247A]

Not permanent how?

[Flex247A → actionfromafar]

Because the compiler ends up looking at all the functions anyway, only for the linker to discard them all.

On: No more blurry fonts in Linux (2023)

Quite likely no, as even grayscale antialiasing is going to look amazing in 4K.

macOS has grayscale antialiasing on by default.

Can someone comment on the effect lcdfilter has?

Seems like full hinting + RGB antialiasing is the way to go on non 4K displays.

Hello! Going through your tutorial and it's been a great ride!

Thanks for the good work.

I am a beginner in graphics programming, and I came across this amazing frame profiler.

This blows my mind. It's so fast and responsive I never expected a WebAssembly application to be!

On: GPU Debug Scopes

What are other cross platform (as in cross-GPU) tools other than RenderDoc that can show GPU debug info?

I found Microsoft Pix, but it's not very useful for Vulkan except showing some performance counters.

[jms55 → Flex247A]

Just RenderDoc really. PIX is DirectX only, and everything else is vendor specific.

I don't really know why you wouldn't just use your vendor's tooling though. The only thing I use RenderDoc for is I find debugging with it a bit easier than NSight when I need to find a problem, but for anything performance related I use NSight (and would use PIX as well if Nvidia didn't gimp it).

Oh also Intel's IGA I've found to be very buggy as well, so I avoid that.

[skocznymroczny → jms55]

Tools may be vendor specific but they're still portable. I use Intel GPA on my AMD card with no issues, I just don't get the extra counters and features Intel GPUs might get.

[gmueckl → jms55]

What's AMD's equivalent to Renderdoc these days?

[Cieric → gmueckl]

AMD has some tools for debugging performance related issues called Radeon GPU Profiler/Analyzer and gfxreconstruct (mainly just a replay tool, but can help when comparing across cards), but for debugging shaders running incorrectly on our hardware we use and support both render doc and Microsoft PIX.

[kiririn → gmueckl]

To my knowledge they don’t offer a frame debugger any more

On: You can contribute to KDE with non-C++ code

[Flex247A]

Honestly, the most welcoming open-source project I found was Blender. They are quite open to criticism, and follow ups are timely.

Only contributed a couple of fixes, but the experience was great overall.

I would like to thank the developers for keeping the codebase maintainable!

It was very approachable for me to fix a few UI bugs a couple of months back.

For me, contributing to a large project feels great, knowing that people will get to run my code (even though the changes are minor).
