Comment #21 by Claus DIETRICH:

I prepared the attached video with verbal comments for demonstration and also provide
you with the original directory of my troubled project. It contains the .settings file
and when you open the project you will have the same szenario like on my PC.

These are my platforms where the problem occurs and the video was made
with the first one:

- i5-3470 CPU @ 3.20GHz with Mint 19.3 Mate
- i7-3770 CPU @ 3.40GHz with Mint 20.2 Cinnamon
- I5-4590 CPU (Linux VM on a Windows Host) with Mint 20.2 Cinnamon
- Very old and slow 32 Bit laptop (didn't check the CPU) with Mint 19.1 LXDE

However, the following raised my attention and may be important for tracing the bug:
I now have a project-version where the short-keys don't work and which has only 3 open
editor tabs. One of these contains an opened png bitmap. On the right upper side of
the IDE I can see 4 tabs, where one of it is called "Clipboard". Below this it shows
two items in some kind of listbox where the upper one is titled "System-Clipboard ...)
The according screenshot is attached hereto.

1. Why are png graphics sometimes put in the "system clipboard" without any action and sometimes not?
2. Is this clipboard the same which is used by the short keys (OS clipboard)? 
3. How could the red selection frame appear without any previous action?

After I removed the png-tab and reloaded the project the short-keys worked.
I think that the clipboard action of the IDE graphics editor or at least
the loading of PNGs could be a potential reason for this bug and I suggest
to direct the focus on this.

Since I didn't understand the purpose of this bitmap clipboard and a few
observations, I was not able yet to generate a more advanced theory or present
a more pinpointing reproduction of the bug.
