The cursor flickers (Qt5)

Dear Sir

I would like to ask you about the screen display when using Qt 5.

Customers confirmed the demo of Qt 5 using MCIMX6SX-SDB.

The screen display seems to have no problem but the cursor seems to flicker.

Q1.

Do you know what causes the cursor to flicker?

Q2.

Is there any way to suppress cursor flicker?

Best Regards,

Eishi SHIBUSAWA,

Hi Eishi,

I have selected the below option:

Device Drivers -> HID Devices -> Special HID drivers -> HID Multitouch panels as an embedded driver (*) in my Kernel configuration, and then I have added my touchscreen's Vendor ID and Device/Product ID to my kernel drivers table and rebuilt the Kernel. My touchscreen is working as expected now.

But for mouse, similar problem is observed sometimes when using a low-speed USB devices such as mices and keyboards. Try to connect your mouse and keyboard through an external USB Hub.
