Bug #: 29496 Summary: Mouse doesn't release when moving/resizing Steam window Product: Wine Version: 1.3.36 Platform: x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: wine@placesthroughtime.com Classification: Unclassified
The Steam window, when resized or moved shortly after changing tabs, ex. from Store to Library or visa versa, will act as though the mouse has not been released after it has been and will remain in its state of resize/move window.
Possibly also related to this, shortly after starting steam and attempting to move the window occasionally the mouse will stick but the cursor will move itself to above the Steam window and any attempt to move back within the window will force it away from the cursor.
