SUMMARY *** Hovering mouse pointer on truncated file names (from one to another) crashes the black box showing the name. STEPS TO REPRODUCE 1. Get a few photos with long file names that will be truncated (with "...") in Dolphin 2. Hover slowly the mouse pointer from one to another file name 3. Observe the "blinking crash of the black box" OBSERVED RESULT The truncated names, i.e. "the black box with full name" don't display full name, black boxes overlay one another and blink heavily. Just a blinking-crash of that "black box with full name". EXPECTED RESULT Not crash the truncated file name in black boxes while hovering mouse pointer from one file name to the other file name.
