Platform: Arch Linux

The top file is the .desktop file in question, the bottom file is the image
used as the icon for the top file. Selecting and deselecting bottom file does
not cause lag, while the top file does.
SUMMARY
Selecting a .desktop file with a large icon on the desktop causes extreme lag.
STEPS TO REPRODUCE
1. Create a .desktop file with "Icon" set to a large file (over 2MB causes
noticable lag on my system, an 18MB png was used for the video)
2. Select and deselect the file on the desktop
OBSERVED RESULT
Doing this repeatedly can cause 1 core to be pegged at 100% for extended
periods of time.
EXPECTED RESULT
No lag
