I was using Inkdrop then I pressed F11 to go Fullscreen and my screen got messed up, seems like the layers are cloned and they are overlaying themselves.
I do not use any plugin, only the default ones and the translucent effect.
Thanks for the report. That’s weird.
What if using the default dark theme without the acrylic background effect?
Note that the acrylic background effect is experimental and not stable.
