Research direction

No source file or test is named in the report. Start by reproducing the resize loop on X11 with two monitors using different DPIs, then trace the window move and resize events; done means dropping the window between those monitors no longer causes continuous resizing.

Description

B - bug DS - x11

It seems like there's an issue when a Window is dropped between two monitors with different DPIs, which leads to the window constantly resizing between the two sizes without any user interaction.

I'd assume this is because the new bigger size causes the window to get thrown back on the other screen, which changes its size again to then move it back on the original screen (which continues forever).

@murarth I believe this isn't the first time an issue like this was reported, are you aware of this getting fixed in the past? Unfortunately I can't find anything.
