Simple systray icon app to suppress intel videocard DPST screen dimming
Modern (2018...2021 years) linuxes and freeBSD (since 13.0) have annoying bug in i915 videocard drivers - screen dims after 1 second after last redraw. This is an intel power saving feature named DPST, and this feature is enabled and cannot be disabled in recent drivers.
This app is a simple workaround for this annoying behavior.
Working principle: we have two barely identical systray icons, and change them every 0.25 seconds to force screen redraw. For human eye it is a simple and static asterisk in systray, but screen redraws.
