1-sized windows
Classification: Plasma

Status: REPORTED

SUMMARY
[Sorry if wrong component or product.]
KWin on X11 allows windows to be extremely small, and window decorations follow
suit, resulting in nearly invisible windows. Haven't tried on Wayland.
STEPS TO REPRODUCE
1. Execute the following PyQt code, preferably on a high-res or large display:
import sys
from PyQt5 import QtWidgets as w
app = w.QApplication(sys.argv)
wdg = w.QWidget()
wdg.resize(1, 1)
wdg.show()
2. Try to find the window you just opened
OBSERVED RESULT
The window is extremely small, making it very hard to find and interact with.
EXPECTED RESULT
Window decorations remain visible around the window. Not sure what to do with
windows that have no decorations.

ADDITIONAL INFORMATION
KWin sometimes resizes a window to such a size by itself, which seems to be
associated with switching between two screens with vastly different resolutions
and a layout combining those.
