When using Motif based applications or xterm, on occasion, the mouse moves VERY VERY VERY slowly or not at all. Many times, when I press a mouse button, the event is ignored. [Weird report: with motif operations, many times the button event is registered (you see the button recess) but the action to be taken does not occur...if I hit a return to fire off the default button action, things work. Half-assed guess, the system sees the button-down event, but the button-up event is somehow lost or mangled, or outside the region, so the action does not complete. Motif may be seeing button-down/button-up events separately instead of a singular button-click event.] If I had to make a wild guess, I'd say that the system is dropping mouse events (both placement and button events) like mad! Maybe 30-50% of them come through at some times, other times, it's 100% solid. I think this is related to PHK's changes that caused the application slowdown other folks have seen. I have not seen any slowdown for things like icon drawings, rather, just mouse events are lost. I have not had a chance to see if this occurs with other serial port events, as I don't have anything else hooked up to the other serial port. >How-To-Repeat: run -current as of 21 march or last night put a serial mouse on one of the standard COM ports fire up a local X session use it for a few hours, watch, intermittently, mouse events get dropped. open up a netscape window, a plan window (motif) and run fvwm2 and watch things get really bad when you cross from say a motif app to an xterm window. >Fix: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
