Unexpected grid potential caused by seaborn or scanpy

[DingWB]

When other packages are imported, such as seaborn and set some kind of style, there would be a unexpected grid in heatmap

import os,sys
%matplotlib inline
import matplotlib.pylab as plt
import pickle
plt.rcParams['figure.dpi'] = 100
plt.rcParams['savefig.dpi']=300
plt.rcParams['font.family']='sans serif'
plt.rcParams['font.sans-serif']='Arial'
plt.rcParams['pdf.fonttype']=42
import pandas as pd
from PyComplexHeatmap import *
import PyComplexHeatmap as pch
print(pch.__version__)
import scanpy
#import seaborn as sns
# sns.set_style("whitegrid")
# sns.set_style("white")

df_row=pd.read_csv("df_row.csv",index_col=0)
df_row.spatial_domain=df_row.spatial_domain.astype(str)
df_col=pd.read_csv("df_col.csv",index_col=0)
df_col.chromosome=df_col.chromosome.astype(str)
data=pd.read_csv("cnv_mtr_filtered.csv",index_col=0)
df_col=df_col.sample(500)
data=data.loc[:,df_col.index.tolist()]
data

plt.figure(figsize=(10, 5))

right_annotation = HeatmapAnnotation(
                **,
                       axis=0)

top_annotation = HeatmapAnnotation(

                label=anno_label(df_col['chromosome'],merge=True, rotation=90),
                chromosome = anno_simple(df_col['chromosome'], add_text=False, legend_kws={'frameon':False}, 
                                         colors= dict(zip(np.arange(1,23).astype(str),['#5daab4','#000000']*11)), 
                                         legend=True), axis=1)

cm = ClusterMapPlotter(data=data, 
                       vmax=1.02, vmin=0.98, 
                       top_annotation=top_annotation,   
                       left_annotation =right_annotation ,
                       cmap='RdBu_r',  
                       row_cluster=False, col_cluster=False, 
                        col_split = df_col['chromosome'], 
                       col_split_order = [str(i) for i in list(range(1,23))],
                       col_split_gap=0.4 
                      )

When use sns.set_style("whitegrid") or change setting in scanpy:

import scanpy
sc.settings.verbosity = 3 
sc.settings.set_figure_params(dpi=100, dpi_save=300,
                              facecolor='white', figsize=(4,4))

An unexpected grid would appear:

When set sns.set_style("whitegrid") or in default, the heatmap looks good:
