Hello,
Im recently implementing a freetype text rendering example and found out that it starts eating process memory on each glDrawArraysInstanced call. Memory consumption is just growing with no deallocation. It is not happening on RTX5070 or AMD hardware. All my tests are done under windows 11 / recent available drivers.
