Bug/Issue black lines around mouse cursor

(1)
From time to time you see for a very short amount of time you see black lines around the mouse cursor. Looks like alpha of mouse cursor image dont get properly blended sometimes. I cant take a screenshot, hope someone can reproduce.
This also may be a driver bug. I have no other Linux box to test this with another graphics vendor.
This also may be related to:

Game starts always in borderless windowed mode for me. If you select fullscreen mode, game puts you in windowed mode instead.

Dropdown menu of resolutions is only kept elapsed as long as I press the mouse button. If you release too early you probably end up with a resolution you acutally didnt want.

Looks like nobody interested, updating though.

Ive updated now to Xorg 1.18.4 which should include the patch to fix the mentioned bug but it didnt help. Thus it looks like this has nothing to do with it.
I really would like to take a screenshot, but its not possible. Those black lines are only visible for a very short time.

This looks has been fixed

Things getting worse if you try scrolling the dropdown menu with the mouse wheel. Looks like it doesnt have focus and scrolls the whole menu instead. Attached is a screenshot with resulted mess.
Really dont now why you implement it this way, why dont you let the dropdown menu open upon you clicked on it?

Edit:

Thanks that someone recorded a video, you can actually see what I mean between 0:43 and 0:45. So it seems that this issue is even there on mac. And you can see it better when playing in low res.

Wouldnt it be better if you keep the resolution menu elapsed when its clicked? You can give the menu focus thus scrolling with mouse wheel would be possible.

 

Did I anything wrong here? I saw bug report with less details and almost no description. Is there anything I can do, or do I get simply ignored?

 

You're not being ignored. It's just hard to reply to everything, and some issues are more urgent than others.

1) I'm not sure entirely what you mean. I've seen a short black line appear below (and only below) the cursor for a split second once, but not black lines around the cursor. Perhaps you could modify a screenshot to show what you mean?

2) Yes this should be fixed now.

3) We know about this. Drop-down boxes act weird in the Windows builds too. It's in our bug tracker.

 

I guess the cursor is just a bitmap image, I see two lines appearing, like you said in a blink of a second, appearing on the right and the lower side of this "image".
If you watch the video I linked before you can see this appears even on MAC. The lines are just brown. (just make sure, you watch it in high quality, otherwise you cant see it)
