QT6 is one of the GUI building blocks that Calibre uses.
Old Graphics drivers seem to have issues with this version (I have a simple, ATI fanless Graphics card in my older Dell that won't work with the viewer (and minor issues with the main GUI). 7.16 uses the olde QT5... That works for me, I just can't run the Latest Calibre on that system.

Years ago, I had to retire my AMD Athelon mainboard because the modern code required something the CPU did not support. There is a point where old hardware just can't meet the needs of modern apps.
