I’ve installed the nightly build KiCad on Ubuntu 21.04 (x64) and during first run clicked to use hardware acceleration for it. Unfortunately, it seems to raise a bug as on the screenshot below:
I found it can be rolled back if I go
Schematic editor >
Display options and select the

Rendering engine, but these changes are there only until the next start of eeschema. How to make them permanent?
