Bug ID: 418818
Summary: Multimonitor setup - videoplayers not properly
displayed if fractional scaling is enabled
Product: kwin
Version: 5.18.3
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: core
Assignee: kwin-bugs-n...@kde.org
Reporter: kde-b...@cyborgsociety.org
Target Milestone: ---
SUMMARY
video area is at unusual place and controls are displayed multiple times
(tested with vlc, dragonplayer, smplayer)
multimonitor setup
- laptop screen 1920x1050
- external hdmi connected screen 5760x2160
- fractional scaling
This is not true
- with a single monitor enabled and fractional scaling enabled
- with both monitors enabled and fractional scaling disabled
I didn't recognize unusual things in other programs (ex. videos in firefox are
working).
VLC
- resized on laptop screen
- the video is croped at top
- black space between video and controls
- controls duplicated 3 times above each other at the bottom of the window
(all three contros are functional)
- resized on external screen
- video tends to be far left (only visible with a big window) or not visible
- moves left if window height decreases
- black space right of video
- controls duplicated up to 3 times (depending on window widths) beside each
other at the bottom ob the window (all three contros are functional)
- only the right part of controls is visible (audio control and right part
of video progress slider)
- if a window is draged to the other screen the window keeps its content
(applies to all players)
smplayer
Same behavior as VLC but controls appear only two times
dragonplayer
- resized on laptop screen
(description of window content from top to bottom)
- ~lower third of controls
- video cropped at top
- 3x black bar with twice the height of the status bar (seperated by gray
line)
- second status bar
- black or artifacts containing bar with same height as status bar
- status bar at the bottom is displayed correctly
- resized on external screen
- same as VLC
