GNOME Desktop Causes My Website’s Browser Interface to Freeze During Extended Sessions

[benstokes]

Hello GNOME Community,

I am currently experiencing one specific problem with my website when it is accessed through a GNOME desktop environment, and I am hoping someone can help me determine whether the issue is related to the desktop environment, graphics stack, or browser rendering. The problem is that after keeping my website open and interacting with it for an extended period, the browser interface can become noticeably unresponsive and eventually appear to freeze. The website initially loads normally, and users can scroll, click buttons, open menus, and interact with the page without any problems. However, after continued interaction with the site, the page can stop responding to mouse clicks and scrolling for several seconds or become completely unresponsive until the browser tab is refreshed. The same website remains responsive for much longer when tested in other desktop environments, which is why I am trying to understand whether something in the GNOME graphical environment could be contributing to the behaviour.

The website contains several interactive components that rely on JavaScript, animations, dynamically updated sections, and browser-rendered media, but there is no single page element that consistently triggers the problem. The browser itself does not immediately crash when the freeze occurs; instead, the tab appears to stop responding while the rest of the desktop continues working normally. In some cases, switching to another application and then returning to the browser makes the page responsive again temporarily, while in other cases I have to reload the page before interaction returns to normal. The issue is therefore not a complete GNOME desktop freeze, but rather a browser tab becoming unresponsive while displaying my website. Because the problem appears only after extended use rather than immediately when the page loads, I suspect that accumulated rendering or graphics activity may be involved.

I have already tested the website using different browsers available on the same GNOME system to determine whether the issue is tied to a particular browser engine. The behaviour is not identical across every browser, but the most noticeable freezes occur when the browser is using hardware acceleration. When hardware acceleration is disabled, the website appears more stable during longer sessions, although rendering performance is understandably reduced. This observation makes me wonder whether the issue could involve the interaction between the browser’s GPU acceleration and the GNOME graphics stack rather than a normal JavaScript error in the website itself. I have also checked the browser console during the problem and do not see a clear JavaScript exception that would explain why the entire page becomes temporarily unresponsive.

Another reason I am having difficulty diagnosing this is that the website uses several CSS animations and dynamically updated interface elements that remain active while the page is open. I have tried simplifying some of these elements and reducing the number of animations, but the problem still appears after sufficiently long sessions. The browser’s memory usage increases somewhat over time, although I have not yet determined whether that increase is abnormal or directly related to the freeze. The GNOME desktop itself continues responding normally during the incident, and I can switch between applications without difficulty. What appears to stop responding is specifically the browser’s rendering and interaction with the website, which makes me unsure whether I should investigate the web application code or the underlying graphics environment first.

I have also tried reproducing the issue on a clean GNOME session without additional desktop customisations, but I have not yet been able to establish a completely reliable reproduction sequence. The problem is more likely to occur when the website remains open for a long period while the user scrolls through dynamically changing content and interacts with several components. Reloading the page immediately restores normal behaviour, which further suggests that the problem is related to the state accumulated by the browser during the session rather than a permanent incompatibility with the website. I am interested in finding out whether there are GNOME-specific diagnostic tools or logs that could help identify graphics, compositor, Wayland, or rendering problems when a browser window becomes temporarily unresponsive.

I would appreciate guidance from the GNOME community on how best to troubleshoot this specific browser-rendering freeze when using my website under GNOME. I would particularly like to know whether there are recommended ways to determine if the problem originates from GNOME’s graphical stack, Wayland/X11 behaviour, GPU acceleration, or the browser itself, rather than from the website’s JavaScript and CSS. If there are GNOME logs, diagnostic commands, or browser-related debugging information that I should collect when the freeze occurs, I would be grateful for recommendations on what to capture. My goal is to identify the actual cause of the temporary browser freeze and make the website remain responsive during long sessions without requiring users to repeatedly refresh the page.

GNOME does not control how web browsers allocate resources on the GPU: that is the responsibility of the web browser and the graphics driver. If this only happens on your website, then your website may be using CSS or JavaScript in such a way that it causes some leak.

There are no GNOME-specific tools for debugging this issue: you’ll have to talk to the developers of the web browser engines you’re using, likely by opening an issue and pointing them to the website so that they can confirm your findings.

Thanks for clarifying that. That makes sense, especially since GNOME itself isn’t directly responsible for how the browser and graphics driver handle GPU resources. The fact that the issue seems specific to my site and becomes less noticeable when hardware acceleration is disabled does make a browser rendering or resource-management problem worth investigating more closely.

I’ll focus on profiling the JavaScript, animations, memory usage, and GPU activity in the affected browsers and try to create a minimal reproduction case. If I can reproduce it reliably, I’ll collect the relevant browser diagnostics and consider reporting it to the browser engine developers, along with the test page and steps to reproduce. I appreciate the guidance on where the responsibility for this type of issue actually lies.
