debug builds crash with assert on custom font URL #1132

Closed JulianGro closed 2 weeks ago

JulianGro commented 1 month ago

Adding https://data. as font URL for a text entity, apparently makes debug builds exit with an assert. Apparently, a working URL such as currently https://data.moto9000.moe/nishiki-teki_3.99zhb.arfont also throws an assert.

Hm, debugger's being unhelpful, too much optimization. Will need a proper debug build for this one.

HifiExperiments commented 1 month ago

this was an issue with any font that failed to download (not just links that started with https://data.). we'd end up dividing by 0 when setting the scale. fix here: https://github.com/overte-org/overte/pull/1111/files#r1750914970

it was also a problem during font loading, which is why the working URL also threw an assert
