I found that I had problems upgrading to Buster / Ascii. However, my 
recommendation is maybe not a "fix", but a better workaround. I would suggest 
using a different desktop (such as MATE) for you other desktop choice. 

When I install Devuan, I use the netinstall CD, and MATE is one of the 
choices. I find that it works better than KDE5 when running beside TDE. It 
took me months and months of tweaking to get KDE5 to behave itself enough to 
make my system work. 

After I install the base system, I reboot into MATE, then add Open Office 
(instead of LibreOffice), and usually reboot again, then install TDE, and 
everything has been working almost with few problems for nearly a year; 
especially the past 6 months have seen only a few minor bugs. No such luck 
with KDE5.
