That explains things. Non-focused applications cannot read keystrokes on Wayland.
Since Discord is still running in X11, if you are on KDE you can enable one of these options as a workaround:
Hopefully Discord (or a wrapper for it) will eventually get proper global shortcut support, in which case you can set it right in the KDE shortcut settings.
Not sure if it counts as “budget friendly” but the best and cheapest method right now to run decently sized models is a Strix Halo machine like the Bosgame M5 or the Framework Desktop.
Not only does it have 128GB of VRAM/RAM, it sips power at 10W idle and 120W full load.
It can run models like gpt-oss-120b or glm-4.5-air (Q4/Q6) at full context length and even larger models like glm-4.6, qwen3-235b, or minimax-m2 at Q3 quantization.
Running these models is otherwise not currently possible without putting 128GB of RAM in a server mainboard or paying the Nvidia tax to get a RTX 6000 Pro.
