A bit off-topic: to avoid unnecessary refer and back-ref info to issue/pull requests numbered from 1 to 10, perhaps you can surround stdout in #1244 (comment) containing #1 to #10 in markdown's code block.

as it works here, also with qt 5.15, there is really nothing I can do.
maybe you should try the appimage ? https://github.com/texstudio-org/texstudio/releases/download/3.0.1/texstudio-3.0.1-x86_64.AppImage

Gentoo is a source-based distro. Each package is compiled on the user's computer.

and the source is unchanged ?

Unchanged.
Recompiled 3.0.1 with -O0 -ggdb, now I have slightly more information:

Of course, I can recompile also Qt-5.15 with -O0 -ggdb, but this is rather much work (I have a large number of Qt-dependent programs, e.g., I use lumina desktop environment, and generally prefer Qt over gtk, so that I'll have to recompile it back with -O2 after this experiment).

Forgot to say: when I simply rum texstudio, the splash screen appears and immediately disappears. When I run it under gdb, the splash screen appears and stays until I quit gdb.
