Is that sticky ghost mouse pointer behaviour the same when you are working directly on the DUT rather than over VNC? And also is it consistent with the different Window Managers? When working directly on my DUT (64Bit Bookworm, USB wireless keyboard and mouse and a HDMI monitor attached as well as the SPI LCD), I have not seen the sticky mouse pointer ghost but I have noticed some inconsistent mouse pointer behaviour between the WMs wayfire and labwc. Screen update performance differs with mouse pointer lag and window drag lag - most noticeable when booting directly to the Desktop rather than booting first to the CLI and then invoking the Desktop with the command wayfire or labwc. Booting 64 bit Bookworm directly to a labwc Desktop being particularly bad. That laggy performance isn't present when I boot the same DUT to CLI and then bring up the Desktop with the command labwc. Mouse pointer and window drag returns to being pretty snappy.
Like you, I can't imagine anyone would want to try and use the full feature set of the CST controller on an LCD this small - just the basic features such as a short - long press and scroll capability would probably be the most useful features for simple menu navigation and item selection. Your on screen keyboard seems to be all working OK with touch? That's impressive.
So I wonder if this is a Window Manager thing or perhaps a VNC thing? I'll try both over VNC on my DUT and see if I can reproduce the sticky ghost. But as I'm not using the i2c touch controller on this LCD then maybe not?
