[BUG] Claude Desktop Windows MSIX - screen flickering every ~15 seconds

Note: this is a Claude Desktop app issue, not Claude Code CLI.
I'm filing here as there is no separate repo for Claude Desktop bug reports.

I have the same strange issue. But for me it flickers every second. not just the App, but the entire screen. Not sure if this is an OLED issue? but it only happens with the Claude app. It flickers slightly, not to total white, the entire screen gets 10% brigther or so.

Same issue. The whole screen flickers every so often, It does it less if my second monitor is off.

Seeing the same on random Windows-based laptops

I was able to fix this issue which seems to affect all modern Electron apps by disabling "V-Sync Fast" for the Claude app in the NVidia control panel. This completely eliminated the flickering in the Claude for Desktop (Windows Electron app.)

The flickering also happened in Google Antigravity, also Electron, and creating the same override profile fixed that too.

I do not know if ATI GPU drivers have similar settings for V-Sync, but might be worth checking if you have the constantly flickering and rendering bugs in Electron apps.

Thank you for this; unfortunately this did not fix it for me (Windows 11, 3070). Its very annoying to the point i am avoiding it largely.

Thank you Nikolas! I don't have NVidia but AMD, however following the same logic, an with the help of Claude Code :) I could solve this issue as well;
Thanks again!

God bless you sir!! I have been experiencing this since I have downloaded the desktop app.

I was not able to get the flicker even with the control panel setting. It appears on my 240HZ OLED but disappears once I move Claude to my second screen which is only 60Hz.

Uncheck the "Enable settings for the selected display model" in "Set up G-SYNC" menu (NVIDIA Control Panel).

I can give that a try but I also want G-Sync for other applications - I have not bought a 240Hz monitor for a browser and Claude. It seems it is something wrong with Electron apps on Windows rather than my setup?

Same issue for me on Samsung Odyssey 57" - running latest firmware 1009.2. Vertical sync fix didnt work - the display specific settings part worked but this is far from ideal - the claude app's interaction with gsync via electron seems broken to me.

Closing for now — inactive for too long. Please open a new issue if this is still relevant.

For ppl having this flickering issue with Claude Desktop on high refresh monitors and/or G-Sync monitors.
The V-Sync setting will not work, I found a working procedure but it's kind of confusing. make sure you follow the step by step below exactly even if it sounds counter intuitive(!), Nvidia control panel is old software and it does some weird stuff sometimes.

Follow these steps exactly:

• Close Claude Desktop and make sure it's not still running in taskbar (really close / stop it).
• Open Nvidia Control Panel
• Manage 3D settings
• Program Settings
• Add Claude (shown as Claude_pzs******)
• 1) look for the "Monitor Technology" and select "Fixed Refresh Rate"
• 2) look for "Preferred Refresh Rate" and select "Highest Available"
• Leave everything else for Claude on "use global setting"
• Click Apply
• 3) look for "Vertical Sync" and select "use global setting"
• Click Apply again
• Notice that when scrolling through the settings ONLY "Preferred Refresh Rate" is changed and set to "Highest available" The other settings you changed are set back to "use global setting" this is your verification that it worked. (see screenshot)

Open Claude Desktop and enjoy
