My Fences just was updated to 5.88 revision 8 today (installed earlier, then a fresh reboot this morning), and I'm noticing performance regressions when using Peek. When I invoke Peek, whether by clicking the hot corner (my typical use) or by using a keyboard shortcut (atypical, but tried it to see if it'd make a difference), I'm seeing the following new behaviors...
* The background desktop image for my non-primary monitor disappears...it just goes to black (regardless of whether a fence is open) until Peek is dismissed
* Hover effects inside a fence are sluggishly responsive to mouse movement
* Double-clicking to launch an application inside a fence takes an unexpectedly long time
* Probably related, in Task Manager, Windows Explorer jumps to the top of the process list when sorted by CPU usage, settling at 2-3% (of a 24 core CPU), whereas it's typically reporting 0% without Peek
If I open a fence without Peek, I see none of these problems. I use Peek quite a lot, so I'm quite certain this is new behavior.
I'm running Windows 11 Pro N, 24H2, build 26100.3194.
