Hi there! Unfortunately, I’m not familiar with this problem nor do I know of a fix. 😦 I did a quick google search which led me to a Leefish thread, but it doesn’t specify with whether or not the issue ever got fixed for the user. You can try looking through the thread and seeing if some of the things Kiri suggested may help you? It’s worth looking through the Leefish forums in general – Kiri is a real expert when it comes to graphics card stuff. I’m sorry I couldn’t be of more help! I hope you’re able to get it fixed. ❤
(maybe one of my followers has an idea?)
