Graphics corruption when running out of VRAM

[Deniil]

I have a RadeonRX in my X1000, which is (also) (sadly and strangly) limited to 256MB VRAM.
I use UHD (4k) reslution in 32 bits. All fine, except that I often run out of VRAM.

When VRAM runs out, Picasso96 is supposed to defrag and swap out some bitmaps to RAM, says Hans de Ruiter, developer of the Radeon drivers. However, this does not seem to work correctly but results in small or big graphics corrupts all over the place. Trashed icons, unreadable menus, wiped out toolbars, etc.

The damage is permanent and cannot be "painted" away unless it is inside a normal window that is able to redraw itself manually.

I have never ever seen this before until I installed the "Experience Pack 2" or whatever it was called that contains the new RadeonRX driver and other stuff required for this to work, and the RadeonRX card. Hans de Ruiter says it's most likely not his fault in the driver, but a P96 bug.

Adding a few images to show the problem. I have more examples.
I'm happy to betatest, but all you have to do is run out of VRAM. Put "%mgm/%mgtmMB Video" in the Workbench title to see.
