Created attachment 1594655 [details] screen capture of the rendering issue Description of problem: In Fedora 30 Silverblue when snapping firefox from one half of the screen to another, the page is not rendered properly with almost a white meshlike overlay. I have added a few screenshots of the issue. Version-Release number of selected component (if applicable): Fedora 30 Silverblue Version: 30.20190728.0 How reproducible: Always Steps to Reproduce: 1. Open firefox 2. Super + left/right arrow to snap firefox to one side 3. Super + opposite direction of step 2. Actual results: Firefox snaps to other side but there are rendering issues with the entire window. Expected results: Firefox snaps to other side and renders correctly. Additional info: Unsnapping(Super + down arrow) and maximizing(Super + up arrow) the firefox window fixes the rendering issue until you perform the reproducing steps again.
I believe it's caused by webrender/gl acceleration and your gfx drivers. Please attach your about:support.
