This page tracks the "Errata/Known issues" that are specific to the the Plasma X11 session: significant quality-of-life annoyances, significant problems with workarounds, etc. It is the X11-specific companion to Plasma/Wayland Known Significant Issues.
X server
- If the X server crashes, all apps are killed
- If a context menu is open, it blocks automatic screen locking and global shortcuts
- No isolation between processes; any app can spy on what other apps are doing
- No protection from malicious apps secretly recording keystrokes or the screen, etc
Multiscreen/scaling
- No support for mixed screen scale screen arrangements
- No support for mixed refresh rate screen arrangements with the compositor active
- No support for adaptive sync with multiple displays
- When screen arrangements change, Plasma and QtQuick-based apps frequently crash: https://bugs.kde.org/show_bug.cgi?id=414805 + https://bugs.kde.org/show_bug.cgi?id=473602 + https://bugs.kde.org/show_bug.cgi?id=446987 + https://bugs.kde.org/show_bug.cgi?id=456947
- With a global scale greater than 100%, maximized windows leave gaps around the edges: https://bugs.kde.org/show_bug.cgi?id=414522
- With a global scale greater than 100%, cursors, splash screens, and icons in Plasma context menus, and Plasma popup corners are too small: https://bugs.kde.org/show_bug.cgi?id=422548 + https://bugs.kde.org/show_bug.cgi?id=443607 + https://bugs.kde.org/show_bug.cgi?id=356446 + https://bugs.kde.org/show_bug.cgi?id=422559
Plasma
- Firefox and Plasma can deadlock one another and both hang when copying something to the clipboard in such a manner that also shows a notification: https://bugs.kde.org/show_bug.cgi?id=446581
- Bottoms of notification popups sometimes get cut off: https://bugs.kde.org/show_bug.cgi?id=464029
- "Keyboard layout changed" OSD does not work: https://bugs.kde.org/show_bug.cgi?id=408928
KWin/rendering/graphics
- Sometimes windows randomly turn black and freeze: https://bugs.kde.org/show_bug.cgi?id=466771
- No native touchpad gestures
- No support for GPU hot-plug
- No support for automatic screen rotation
- Bad multi-gpu performance in many cases
- No support for HDR
- Apps need to opt into color management, so most look wrong on wide color gamut screens, produce screenshots and screen recordings without color profile tags etc
- Using 10 bits per color completely breaks many apps
- Increased latency and stutter with the compositor active
- No recovery from GPU resets in most cases
- No reliable way to prevent screen tearing
- Enabling adaptive sync requires editing a config file
- KWin sometimes crashes when disabling compositing: https://bugs.kde.org/show_bug.cgi?id=466380
- Touchscreen gestures eat a pixel on their screen edges, breaking Fitts' law when using a pointing device
- Sometimes Overview effect stops accepting keyboard input: https://bugs.kde.org/show_bug.cgi?id=449840
- SDDM virtual keyboard is unusably small: https://bugs.kde.org/show_bug.cgi?id=431949
- Some windows are transparent on launch, then content fills in later: https://bugs.kde.org/show_bug.cgi?id=422596
- Screen locker sometimes randomly falls back to software rendering: https://bugs.kde.org/show_bug.cgi?id=423301
NVIDIA
- When reenabling compositing, sometimes windows begin flickering and flipping upside-down: https://bugs.kde.org/show_bug.cgi?id=450301
System Settings
- Acceleration profile settings of Mouse & Touchpad KCMs are missing depending on how you open the KCM: https://bugs.kde.org/show_bug.cgi?id=448953
