Reduce memory consumption by 10x

[its5Q]

By default, the Avalonia library uses GPU acceleration with OpenGL / Direct3D / Vulkan. This is quite overkill for an app as simple as this with not much graphics going on, and it turns this lightweight app into a 500MB RAM hog from all the GPU libraries being loaded. This PR switches Avalonia to software rendering, cutting RAM usage from 500-550MB to 50-60MB.

How come its running way less on mine? I've never seen the app use more than 100mb of ram.

Task Manager doesn't report actual memory usage. Use System Informer or your profiler of choice for this:


It's mostly commit memory from big NVIDIA and OpenGL libraries (so it also might be less on some GPUs).
So it's not reported in Task Manager in the total memory usage, but is part of the commited memory shown. And if Windows runs out of commit memory, it will start killing processes, even though Task Manager could happily tell you that you only have 70% used memory.

Git checks fails with this small change.

[its5Q]

Huh, weird. On my machine it passes all tests including the one it fails in the CI checks.

[FN-FAL113]

I re-ran the tests again and it passed, gh actions might be broken last time lol since I rerun it multiple times and it fails.

Have you tried this on any linux distro? Does it run without issues?

[its5Q]

Let me try in WSL real quick, but it should work because this option is only applied for Windows.

[its5Q]

Runs and passes tests, looks good

[FN-FAL113]

Sorry, I mean if the app compiles properly for linux config (dotnet publish -c release -r linux-64) and is functionally tested by opening the compiled app and using it.

[its5Q]

Oh, yeah, it does, I just didn't attach the screenshot of the GUI, but I tested it under WSL (you can launch GUI apps in WSL). Right now I'm out of the country, so I can't help further
