The screen goes crazy when you move the cursor

I don't know if it's related to the skin (I use Tiger), but since I started using jAlbum (a year ago) after some time the display on the screen starts to go crazy when moving the cursor. Only restarting the program helps.

Correct

Could be a graphics card problem. See this thread from a while ago

Oh, yes, this brings back old memories. In the posted link, a couple of posts down, I'll put my money on using the -Dsun.java2d.d3d=false flag as the fix.

You can try switching the look and feel to system standard under Preferences. Please report if that works. We actually believe this is a graphics card bug that mainly affects some NVidia users. Please report to NVidia. jAlbum, being a Java software, doesn't have direct access to the graphics driver so it's unlikely that a jAlbum bug causes this. If it isn't the graphics driver, then it's likely something within the Java engine, but the Java engine is used on billions of devices, so I assume the best way forward would be for the graphics driver manufacturer to update their driver.

A workaround is to modify jAlbum.ini and add the following to the VirtualMachineParameter list:

-Dsun.java2d.d3d=false

. This will likely work around the problem, but at the expense of graphics performance.

You were right. It took me a while to test jAlbum with this addon, but it did help. I have a not so bad graphic card RTX 3070, so I am not afraid of a drop in performance. Thanks.

Good that this workaround works at least.

It's an equal opportunity screw-up by the writers of graphics drivers. When I first encountered this, about ten years ago, I believe it was a Radeon card that was the culprit. Eventually, a driver update fixed it. But now it looks like someone at NVidia has stumbled into the same minefield. Or maybe it's the same guy, and he's switched employers!

I see the synonym of this flag set with Netbeans as well (-Dsun.java2d.noddraw=true), so it's at least not ONLY jAlbum that triggers these artifacts, but a very well known IDE as well (initially developed by Oracle/Sun)
