Screen gets dimmer and dimmer

I observed it happening gradually. It seems that as I edit regions more, the screen slowly starts to dim. I have used the program in good lighting, so that isn’t an issue.
I am concerned that i am only getting a response about this now. There are others aside from me who are having this problem with the screen dimming. Have they said anything to you? I thought that Frieder said in a previous post that you guys were aware of this problem. This was a month ago. This doesn’t sit well with me. The workaround of rebooting the program is not practical at all. Let me state again that I love the program and will not delete it. I just think that this issue is being ignored up until now. Other apps that I use have been more actively doing maintenance updates when needed. Thank you for your response.
