OS: Linux
Status: REPORTED
Severity: normal

Konsole turning black upon hiding its border
SUMMARY
Recently, whenever a window's border is hidden (or restored), the entire window
turns black. This started to occur only during the past few months. As can be
observed in the attached screen-captures, the window could be reviewed only
after performing a minimize/restore or a maximize/restore operation. This
observation was made while using KDE in X11.
STEPS TO REPRODUCE
1. Open a window.
2. Hide the window border (either by right-clicking on the title bar or
pressing Alt+F3 and selecting "More Actions > No Border"). Window observed to
turn black.
3. Minimize and restore the window through its icon on the panel. Window
content is visible again.
3.1. Alternately, maximize and restore the window by using the shortcuts
Meta+PgUp and Meta+PgDn to make the window content visible again.
4. Now, unhide the window border (by pressing Alt+F3 and deselecting "More
Actions > No Border"). Window (except the title bar) turns black again.
5. Repeat either step 3 or 3.1 to make the window content visible again.
OBSERVED RESULT
A visible window turns black upon hiding/unhiding the window's border.
EXPECTED RESULT
Window content should have been visible instead.
