[SOLVED] Background color of QPushButton, in Python; Fedora vs. Ubuntu

Wondering what I might be dong wrong. I'm running Fedora 32 and 33, and Ubuntu 20.04 and 20.10, all updated. The code below properly colors the buttons under Fedora, but not under Ubuntu.

Code:

from PyQt5.QtWidgets import (QTableWidgetItem, QLabel, QLineEdit,
    QVBoxLayout, QWidget, QPushButton,QGridLayout, QTableWidget,
    QFileDialog, QApplication, QHBoxLayout, QButtonGroup)
from PyQt5.QtCore import Qt
...
for idx, img in enumerate(["←", "→", "↑", "↓"]):
            btn = QPushButton(img, self)
            btn.setMaximumWidth(20)
            btn.setStyleSheet("background-color: aqua")
            self.xlt_grp.addButton(btn, idx+1)
            hbox.addWidget(btn)

Coloring the background QTextEdit works properly in all cases.

Work-around: set a border in the stylesheet; border:none works. However... this leads to the colored button being shorter than the uncolored button, which is worked around by
fixing the height of the button when it is created.

Code:

xx = self.btn_color_check.size().height()
self.btn_color_check.setFixedHeight(xx)

Code:

btn.setAutoFillBackground ( true );
