I have been seeing problems in Libreoffice Calc since 19.10 days on and off. Either icons disappear or screen is painted, covering parts of the spreadsheet. I am dual booting Kubuntu 20.04 alongside Lubuntu 20.04 and does not experience the problem. Resizing and restoring the window usually takes care of the problem. There is no easy way to repeat it but here is my take:
1- The very first use: Open an existing or read-only document. Closing the read-only and/or LO first use notice should show the problem.
2- Normal use. This seems to occur at random so I enclosed a picture:
Thanks, that indeed solves the problem, though screws up the qt-sie feel. Interestingly, Kubuntu 20.04/10 both carry lireoffice-qt5 and I do not observe this problem. I’ll check LO forums for a clue.
I’ve remembered I saved the different packages installed (I posted it in the Italian Ubuntu forum last month), maybe it could help to solve the issue

I cross-checked the packages Lubuntu shipped with Kubuntu’s (20.04.1). The only difference is Lubuntu has libreoffice-gtk3 whereas Kubuntu has not (I did not check styles, icons, etc). As I have just recently converted my hard disk to GPT from ms-dos, I have no Lubuntu available at the moment. After 3 failures, I ended up with Kubuntu 20.10 and Kubuntu 20.04 with success. I will create a live usb for Lubuntu and try to remove libreoffice-gtk3 package and report the result. Once again, many thanks for your help.
LibreOffice has been no small source of pain for us, based primarily on the VCL which is responsible for a LOT, but most importantly the UI. AFAIK Kubuntu (or rather KDE) has their own sort of proprietary Qt option (the Kf5 one) that brings along a ton of dependencies. We didn’t want to use that, so we opted for the Qt one. Only it seems there are lots of bugs with the Qt one. That’s the long and short of the problems with LibreOffice in general. You can switch the VCL used on the fly (via environment variables) regardless of packages used. If you want something totally stable, just use the GTK3 one, but it won’t be as Qt-sie, which is now my word of the day.
