Hello,
5.2.11-arch1-1-ARCH x86_64 GNU/Linux
After an update I find that the longer my machine stays running, the slower and slower `xfwm` becomes. Seems to bottom out at around 2-3 seconds to switch windows. While the application within that window responds fine. Eg., I'll have a 10 tab Firefox window open, and a xfce4-terminal. Just clicking, or alt-tabbing, between them takes 2-3 seconds. But I can scroll and change tabs in Firefox without any delay, or type in the terminal without any delay like it would if it were a kernel/hardware issue. Sometimes, it never changes focus and both windows will be active/selected in the taskbar but the one I tried to focus does not come to the front. Retrying fixes it.
I've tried disabling the compositor but it doesn't improve.
I've got a list of applications updated since around the time *I think* this started happening.

Xfwm also seems to be taking a lot of CPU time (20-25% when moving a window around). If I wanted to try the previous version of xfwm, can I single it out or do I need to downgrade everything in XFCE?

Side note, since that update conky has also been reporting negative amounts of memory usage:

Rules for problems.
Everyone has problems. Animals have problems. And buildings. And cats, and trees.
Problems are your friends. Treat them well.

All I can tell you is I turned off xfwm built-in compositing and switched back to compton and it seems like the right decision. Things seem way more responsive now and that lag upon switching appears to be gone.

If I `pkill xfwm4` it speeds up immediately. Just slows more and more down and eats up more and more processor as it goes along. Memory usage is nominal, however.
I searched a bit and found this bug, but it's not exactly the same issue.

Did you try the different vblank modes? Did they make a difference?
Offline
I tried `xpresent`, it did not make any discernible difference. I will try the others.
EDIT: xpresent

The proper value is "xpresent" for that vblank mode. (note the 'x')

Sorry, yes, `xpresent`, I was going off of memory.
I've also noticed that at some point during this "slow degradation", I am no longer able to drag windows from one workspace to another by trying to drag a window beyond a workspace's edge. After killing xfwm4 and letting it restart, it works again. I will try and be a bit more scientific when I get a chance.

So I tried all 3: xpresent, glx, and off. The problem eventually appears with all of them.
When I get a chance I'll see if I can profile xfwm and distinguish when the sluggishness occurs.

Try removing xf86-video-intel, quite a few reports noting similar issues with it.
Online
Removed xf86-video-intel, no effect. Still slows down.
I did reinstall it and added
Option "DRI" "2"
to an
/etc/X11/xorg.conf.d/20-intel.conf
Since DRI 3 is now the default. Will see.

Changing the DRI version (or whatever) to 2, from 3, seems to have fixed it. Thanks!

I spoke too soon. Seems to last longer but today after leaving it on all night xfwm4 was pinned at 25% CPU and real slow to move windows around with.

Been looking into this. Found this forum post on XFCE4's website. One poster says:
The delay and high CPU consumption also happens to me with the default theme of Manajaro 18. But if you switch to Adwaita it works fine.
So I am trying a new theme.
I also found another post on xfce4.org that mentions this bug report that sounds like my issue!
