Descriptive Problem Summary:
When the System scaling is set above 100%, the renderer will either show browser Windows too small, while the content is rendered correctly, or it will straight up fail rendering the browser windows.

Numbered Steps to Reproduce Problem:
Run Test build on a system with 100% scaling set.

Connect to the Test build from another system, first at 100% scaling, browser outputs work fine.

Change Scaling to e.g. 150%, notice that the browser windows are either scaled too small or the rendering fails.

See Discord for a test build. https://discord.com/channels/725444629172060262/ 725458744711839873/1336631750754963476

Expected Results:
The browser windows to be rendered properly

Actual Results:
The window being sized wrong or ending up not rendered properly

Does the problem occur:
Every time? Or how often? Every Time
In other games? Yes
In other user accounts? Yes
On other computers? Yes

When does the problem NOT occur?
When not using any screen scaling above 100%. Not feasible nowadays, especially not on 8k and larger screens.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)
Tested on the latest 516 versions.

Workarounds:
Setting screen scaling to 100% and suffer that nothing can be read any more...
