Sentry Crash Report:

Description falling_failing_falling 2019-11-15 18:35:19 UTC 
Application: plasmashell (5.17.2)

Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 5.0.0-32-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:
 I was trying to isntall the latest KDE neon Uswer Edition from ISO on a USB to my old computer.
This computer is not compatible with UEFI.
However, everything goes well during the startup of the ISO.
Then a blackscreen appear with moveable mouse and the " Plasma - KDE crash hanlder "
So we can say that the desktop iisn<t working but the windows are working (even Dolpjhin works).

CPU : AMD Athlon 64 3000+ 
This is a x64 CPU
GPU : ATi Radeon 9250 Series (TUL Corporation a.k.a PowerColor)
This is an old graphic card, however it sup[port OpenGL 1.? and DirectX 8 and 9. 
- Unusual behavior I noticed:
Blackscreen instead of the "live" plasma desktop.
Moveable mouse displayn on screen.
Crash report window.

NOTICE THAT IT WAS REPORTED TROUGH THE OLD COMPUTER.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Please note that KDE Plasma 5.14.? is working on Debian on this old GPU, so it's only the KDE Neon ISO that is broken on BIOS mode on old GPU.

It looks like the newer Qt version in Neon doesn't correctly check for supported OpenGL version. It is also possible that Qt now requires at least OpenGL 2. Please report this issue directly to Qt developers via https://bugreports.qt.io/ referencing the lines I pasted below.
