title of the gif got stacked together about imageio

[rl3418]

Tried again with a white background. The problem remains

import os
import matplotlib.pyplot as plt
import numpy as np

savefol = '/rds/general/user/rl3418/home/imageio/test'
saveflag = True

for i in range(0,10):

fig1, ax1 = plt.subplots(nrows=1, ncols=1, figsize=(16,8))
plt.xlabel('x/Nx*4')#y
plt.ylabel('y/Ny*4')#z
ax1.set_title(''.join(['iter', f'{i:04}']))

if saveflag:
        savename = ''.join([savefol,'/im',f'{i:04}','.png'])
        fig1.savefig(savename, dpi=200)
        plt.close(fig1)
if i%50==0:
    print(i)

import imageio.v2 as imageio
images = []
files= os.listdir(savefol)
filenames=sorted(files)
os.chdir(savefol)
gifname = os.path.join(savefol, 'test.gif')

for filename in filenames:
images.append(imageio.imread(filename))
imageio.mimsave(gifname, images)

setting facecolor='white' resolved my problem
