Didn't see that doublespeak "We value your privacy" banner coming on a website that literally has FOSS included in the domain name. (If you don't need consent, then you don't need a "cookie wall". If you don't do invasive tracking but just regular visitor counting, you don't need consent. Any site with a privacy pop-up is one that wants you to "opt-in" to something that isn't in your interest.)
This is one of those dumb but simple and effective solutions to otherwise complex problem that I just absolutely love. I use Epic Pen on Windows when doing video editing and other media work and I need to line something up close enough. It's rarely worth the effort of duplicating, overlaying and tweaking the opacity of footage just to roughly match two shots and then delete the overlay, but drawing a quick outline on my screen takes like 2 seconds.
KDE -- I guess they want us to call it Plasma nowadays -- still has this feature (it's off by default, but you can enable it in Desktop Effects). It's pretty clunky to use, though: you have to hold down both Shift and Meta while drawing with the mouse. And I don't think you can draw with fire.
Thanks for sharing. Looks like gromit-mpx fixes one of the longstanding bugs in gromit in which new strokes often cause a line across the screen (from the end of the last stroke?).
My daughter invented something similar. It turns out that a whiteboard marker will draw anywhere on a Linux desktop screen, and it's also completely cross platform.
I've actually done this a few times before - it works really well until you write on a screen with a particular kind of high gloss anti-reflective coating, which it damages, and leaves you with visible lines even after you wipe the ink away. Not recommended!
