A quick search of the forum for “appimage” would have turned up:
The day I closed the topic you refer to, the one I’ve linked above was about three weeks old. Only one topic returned from the search would have been more recent, but that one was about scroll bars. The relevant topic was so easy to find I didn’t think I needed to furnish the link.
Looking at your profile, I see you joined the forum the same day you made your earlier post. Perhaps you did not read the FAQ, which contain useful ideas about how to get help.
