VSE Render crash when Zooming timelineto VSE Render crash when zooming timelineAdded subscriber: @lichtwerk
Can confirm this (apparently only happening with mousewheel zoom), will look into it shortly...
... and apparently only happening with a Text Strip rendering (no Sequencer preview window has to be open for this even), crash happening in font handling
hm, seems like
font->glyph_cache
is cleared byUI_view2d_zoom_cache_reset()
somewhere inbetween setting it up indo_text_effect
BLF_size
and actually needing it later inblf_glyph_add
Not sure if there is a good way to lock here? Or just recreate it on the fly [in the case it was cleared]?
