OpenGL crosshair 'ghosting' and incorrect rendering

KDE Debian 12 Bookworm, AMD GPU WX5100, seen on Real HW as well as Virtual Box
VM

Linux vbox 6.1.0-51-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.177-1 (2026-07-16) x86_64 GNU/Linux
PCB design tool TARGET3001! v33 shows two problems with OpenGL enabled:
- Crosshair "ghosting" - moving the cursor around fills the screen with
crosshair artifacts
- Incorrect rendering - graphics is rendered with odd jumps in curves/vectors

This can easily be reproduced by opening the Dice.t3001 file.

The effect disappears if the option "OpenGL instead of GDI+" under
Settings/Options is disabled.

A free version of TARGET3301! can be downloaded here:
