Note: Width and Height are set automatically based on the font_size, but can be overridden. + +Note: RAPL is currently used for Intel CPUs to show power draw with `cpu_power` which may be unreadable for non-root users due to [vulnerability](https://platypusattack.com/). The corresponding `energy_uj` file has to be readable by corrensponding user, e.g. by running `/sys/class/powercap/intel-rapl\:0/energy_uj` as root, else the power shown will be *0 W*, though having the file readable may potentially be a security vulnerability persisting until system reboots. ## Vsync ### OpenGL Vsync - `-1` = Adaptive sync
