### Expected behaviour Just works. ### Current behaviour Crashes on the fir…st call to `caspar::accelerator::ogl::texture::impl::copy_to` ---- ### Steps to reproduce 1. Install AMD Pro drivers 22Q4 2. Start CasparCG server and load a color (LOAD RED) ### Environment * Commit: 2.3.0, 2.3.3 and master * Server version: [e.g. v2.2] * Operating system: [e.g. Windows 11] --- I played a bit with the code here and it seems that its due to the format / type not working properly. When I change format to GL_RGBA and type to GL_UNSIGNED_BYTE I get results but Red and Green channels are swapped. But any call with GL_BGRA Guess it's a driver issue but maybe there is a workaround in CasparCG. Reported that with the AMD driver software 🤞🏼
