    GPU Issues 4.1.4 and 4.2


      I use (on my macbook pro 15", Yosemite) an ASUS 4k monitor and a Apple Thunderbolt display and I have found that after a while (anywhere from 20-40 mins) that SQLDeveloper starts to thrash away at the GPU causing mouse jitter and terrible screen lags. Using istat menu's I can see both the memory and processor (gpu) at 100% usage. If I move the SQLDeveloper window on to the thunderbolt display - then the GPU usage settles back to around 50% for both memory and processor. If I move the SQLDeveloper window back to the 4k screen - within a minute or so - both measures are back to 100% and the computer becomes pretty unusable.
