Bug ID: 374881
Summary: Lags when resizing Qt4 windows on Wayland
Product: kwin
Version: 5.8.5
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: igor.pobo...@gmail.com
Target Milestone: ---
When I resize freshly opened Skype window (either maximized from the tray icon
or just new instance of skype), it only resizes by several pixels (it resizes
the window twice) and then freezes. After randomly moving/resizing the window
several times (didn't manage to find regularity), resize starts working well.
Apparently, this is an issue with Qt4 applications: I've managed to reproduce
it only with Skype and FBReader. It is also an issue with Wolfram Mathematica;
however, not sure which toolkit they use.
I've also tested Qt5 applications with both wayland and xcb platforms
(Dolphin), GTK applications (Inkscape), some Java applications (SweetHome3D) --
all of them work fine.
