Unsolved GUI responds slowly only on some systems.
-
Hi, using debian jessie system to install pyqt5==version5.12.3 GUI. On one similar system the GUI works fast without any issues.
On another system, the GUI is super slow - unsure of why it could be so?
On BOTH systems, i do get a warning (but this does not impact functionality):
qt.qpa.xcb: failed to initialize XRandr qt.qpa.xcb: X server does not support XInput 2 Fontconfig warning: line 146: blank doesn't take any effect anymore. please remove it from your fonts.conf qt.qpa.xcb: QXcbConnection: XCB error: 1 (BadRequest), sequence: 169, resource id: 53, major code: 131 (Unknown), minor code: 47
Since this message is seen on BOTH systems, I do not think this has anything to do with the slowness.
Any insight/tips?

Hi,
