No offense, but if you're really working at this resolution then good luck. This does not look at all like it meets the minimum requirements (https://helpx.adobe.com/photoshop/system-requirements.html) and as such of course there will be all sorts of issues with hardware acceleration and UI drawing. You can try to turn GPU acceleration off in the preferences or take the other route and update your system's graphics driver and configure your screen suitably, but honestly, I have serious doubts it will improve anything given the circumstances.
