I recently reached out to Capture One support for an issue I'm having with OpenCL hardware acceleration on my 5700 XT. I confirmed with them that through running OpenCL benchmarks & verifying OpenCL support is enabled using GPU-Z, but in the end they suggest that my rendering issues (blocky artifacts) are an issue with my GPU drivers or with the GPU itself.
The card is a new Gigabyte Aorus 5700 XT on a fresh (and fully patched) Windows 10 install. I am also using the most recent 20.2.2 drivers and the card is otherwise working perfectly.
While I have seen other forum posts that reference similar issues, I haven't yet found anything from AMD that either acknowledges the issue or points to a fix. Are there any workarounds in place for this issue that do not involve disabling hardware acceleration in Capture One?
