qt.qpa.xcb: failed to initialize XRandr and XInput2 Errors

[brookbot]

Hi,
I'm running Qt5 on RHEL8 and get the following errors when I launch designer as well as my application. Although the applications still work fine, its not how I want to deliver my solution:

qt.qpa.xcb: failed to initialize XRandr
qt.qpa.xcb: X server does not support XInput 2
qt.qpa.xcb: QXcbConnection: XCB error: 1 (BadRequest), sequence: 169, resource id: 53, major code: 131 (Unknown), minor code: 47

Qt Designer 5.15.2

The best info I've found is to upgrade xrandr and xinput extension. Does anyone have a better solution for this? Or am I just trying to use Qt5 with an unsupported distribution?
