Followup to our old article, Evan Hillas released a new version for the latest QNX 6.3 on his QNX project site. The new QNX 6.3.0 Photon VESA driver has added shadowbuffer for faster scrolling and dragging. The driver that this is built from already performs refresh rate setting so this version no longer has the addition for tweaking the display timings.
The driver won't appear in the prefs list of drivers until after a reboot.
WARNING: It gets hit hard if there is excessive amounts of oversized widget "damages".
