Compiling with the default Makefile.std on Debian Buster and running with ./sil -mx11 -- -g , I see that once a creature becomes alert the rendering of the alert indicator obscures the creature's tile. Checking under the debugger, the tiles were being resampled to 10 x 20 from 16 x 16 to match the font that was used.
