Summary: Resizing panels is extremely slow and ramps up a
single CPU core
Product: LibreOffice

Hardware: All
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal

Screenrecording of LO Impress 25.8.1.1
Resizing panels in Impress by dragging them with the cursor is very slow and
happens with a delay of a second or more.
While constantly resizing (i.e. dragging a panel's edge to left/right), one CPU
core goes up to 100% and the fans turn on.
Please see the screen recording. On the left you can see the CPU usage.
Haven't tested it under X11 though.
