Ok, I think I've got this issue figured out.

Following KMines, the patch simply passes in Settings::theme() when constructing the KGameRenderer, however kblocks.kcfg has no default value for the theme, so no theme is loaded. I believe that the proper fix for this is to add a default value to the config file, correct? Alternatively, should KGameRendererPrivate::setTheme() call KGameTheme::loadDefault() when it receives 0-length theme string instead of just bailing?

Note that this bug affects KMines as well: deleting kminesrc from the config directory and then running the game results in no theme being loaded and thus a blank view.

I referred to the KMines source while restructuring the code, as it has various conceptually similar elements (a grid with square cells that are activated by the user during gameplay, etc.)

Particularly on the cells with T-shaped cable junctions, white pixels often appear at the edge of the pixmap during the rotation animation. I would greatly appreciate any suggestions for how to avoid that happening.
