@xkeshav can you include your code?

[recursivezero]

Code is private so unable to share

[sfc-gh-lwilby]

@xkeshav @recursivezero we don't need your exact code, but can you share a minimal example that can be reproduced? I'm particularly interested in the way dimensions are handled on the images and the settings on the the containers.

Hey i have the same issue with this code

        wordcloud = WordCloud(stopwords=stopword,width=800, height=400, background_color="#0e1117",max_words=120,color_func=self.random_color_func)
        wc=wordcloud.generate(text)
        fig, ax = plt.subplots(figsize = (20, 10),facecolor='k')
        ax.imshow(wc, interpolation = 'bilinear')
        plt.axis('off')
       st.pyplot(fig)

Hi everyone! This appears to be a duplicate of #12678, which is a confirmed v1.50.0 regression affecting plots and images.

🔗 Primary Issue

#12678 - "Plots are shown tiny, fixed after maximizing and unmaximizing plot again"

• Status: Confirmed (status:confirmed, priority:P3)
• Same symptoms: Images/plots display very small initially, correct size after layout changes
• Root cause: Width calculation issue in v1.50.0, particularly with fragments and containers

🔧 Workaround

Try using the width parameter with your images:

# For st.pyplot
st.pyplot(fig, width="content")

# For st.image
st.image(image, width="content")

This workaround has been confirmed to resolve the issue in #12678.

📋 Can You Confirm?

@xkeshav @recursivezero @ExodusG - Can you test if the width="content" parameter resolves the issue for you? This will help us confirm this is the same bug.

🔍 Follow the Primary Issue

For updates on this bug and the fix, please follow #12678. I'll close this as a duplicate once we confirm it's the same issue.

[ExodusG]

Yeah, that solves the issue.

[sfc-gh-lwilby]

@ExodusG I am working on a fix as well.
