After a long weekend of vacation and a recovery day, I've uploaded 6.14.0.346.
.346 has one change in it, but it's a moderately major one. When using OpenGL (but not OpenGL ES or ANGLE), Ren'Py now uses GL_BGRA and GL_UNSIGNED_INT_8_8_8_8_REV to upload textures. This is recommended by several sources (
linked here) as a performance boost. On some versions of the Intel GL drivers, it can improve by 10x the speed of the texture upload operation.
Barring an implementation bug, this should be a relatively safe change. Before GLES mode was implemented, we had been using GL_BGRA without anyone noticing.
Two months in, I think we're nearing the end of the release campaign. Unless a truly critical bug is found, I'd like to post this up for a few days of public testing, and then release it.
