Bug ID: 488208
Summary: Xpra breaks under kwin: context menus of remote
applications disappear istantaneously
Classification: Plasma
Product: kwin
Version: 6.0.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Kwin appears to behave differently wrt other window managers with the result of
breaking xpra (https://github.com/Xpra-org/xpra), an application for using X11
applications from remote.
I have the following configuration:
Server: Manjaro linux, KDE plasma 6 with wayland session
Client: same
Running xpra 6.0.1 (latest) on both machines.
On the server I start xpra as a server managing the "virtual" display :101.
Then I start applications in X11 mode using DISPLAY=:101. On the client I
start xpra to attach to the server. The xpra client works as a GTK3
application in the wayland session.
Now, I start VirtualBox on the server on the :101 display. The Virtualbox
window is correctly shown in the client. However, if I right click to open a
contextual menu, the menu opens and disappears immediately, without letting me
use it.
I am being told from the xpra developer that this behavior is not experienced
on other desktops. See https://github.com/Xpra-org/xpra/issues/4246
STEPS TO REPRODUCE
1. Have 2 hosts
2. Assure that they both run a plasma 6 wayland session
3. Assure that xpra is installed on both
4. Assure that Virtualbox is installed on one of them that will be the server
5. On the server run `xpra start :101`
6. On the client run `xpra attach ssh://server/101 --start konsole`
7. On the client see a remote konsole from the server appear
8. In the remote konsole type `VirtualBox` to start virtualbox on the server
9. See the Virtualbox window appear on the client
10. Right click on some object in the Virtualbox window to make a context menu
appear
OBSERVED RESULT
See the context menu appear and immediately disappear
EXPECTED RESULT
The context menu should remain visible until it is used or erased.
