Chrome and Edge flickering/lagging on second monitor (MSI GE75, RTX 2070) - Firefox works fine
Hello. I have an issue with my MSI GE75 laptop running Windows 11 with an RTX 2070. When I use a second monitor Dell connected via HDMI, content inside Microsoft Edge and Google Chrome starts flickering and lagging. Firefox works fine on the same setup. The laptop is MSI GE75 with RTX 2070 and Intel iGPU. The second monitor is a Dell. Browsers affected are Edge and Chrome. Browser not affected is Firefox. I set Edge and Chrome to run on the RTX 2070 in Windows graphics settings. All drivers are updated. All settings are on maximum. The issue is flickering and micro freezes while scrolling or playing videos on the second monitor. This does not happen on the main laptop display. I already tried switching Edge and Chrome to High performance GPU RTX 2070 in Windows settings with no effect. I updated NVIDIA and Intel drivers with no effect. I disabled hardware acceleration in Edge and Chrome which reduces the issue but performance drops. I set both monitors to the same refresh rate 60 Hz but the problem persists. Since the problem only happens with Chromium based browsers and only on the second monitor, I suspect it could be related to how Microsoft rendering pipeline interacts with Chromium hardware acceleration. Firefox which uses a different rendering backend works fine. My questions are: Why does this only happen with Chromium based browsers but not Firefox? Is this related to how Windows and Chromium handle GPU acceleration on a second monitor? Is there a known fix or workaround to make Edge and Chrome work properly on the second monitor? Thank you in advance for any advice.
