** Description changed:
+ [ Impact ]
+
+ When resizing the terminal window, intel_gpu_top may crash if the window
+ becomes small enough. The output when it crashes is:
+
+ intel_gpu_top: ../tools/intel_gpu_top.c:1202: print_percentage_bar: Assertion
+ `max_len > 0' failed.
+
+
+ The proposed fix consists of removing the assert() function and only skip
drawing.
+
+ [ Test Plan ]
+
+ Run intel_gpu_top inside a console
+ Resize the console with the mouse to it smallest size
+
+ [ Where problems could occur ]
+
+ The problem occurs when intel_gpu_top try to draw information on the
+ console
+
+ [ Other Info ]
+
+ This fix should not cause regression on any other feature.
