--- Comment #11 from Sulphur <[email protected]> --- I can confirm that you are correct! If the VCL plugin is set to gtk3, the cursor issue does not occur. (I did have to make sure the libreoffice-gtk3 package was installed to get that to work.) The cursor problem (using the kf5 VCL plugin) does sometimes take a bit of clicking around to appear. But sometimes as soon as you open up LibreOffice it's visible: the cursor is blinking but when it "blinks out" a thin cursor remains. It's not consistent whether or not the issues appear immediately or not. The downside with the gtk3 VCL plugin is that obviously some KDE integration is dropped (e.g., file picker is GTK's), and the toolbar icons are blurrier. But no issue with the cursor that I can see. (I also realized then that when kf5 VCL plugin is the cause of this scrollbar issue, which also does not occur when using the gtk3 VCL: https://bugs.documentfoundation.org/show_bug.cgi?id=145815.)
