hope everyone is fine.
Before I start, I have to say that I have searched a lot for the solution and I have found this, but it doesn't solve the problem, nor does it happen with Google Chrome.
What happens is that some applications, some installed from flathub and others as .appimage, are shown double in the Plank for a few seconds, until the blurred version remains and the good one disappears.
There are some more apps, but this are good examples. How can I fix this, is there a universal solution or do I have to go one by one?
