Under Buster I used to have odd freezing of one standalone unity game. It would freeze for 1 or 2 seconds after each action. Looking at radeontop it would show how it works, and once it freezes all stats would go to 0.
After upgrading to Bullseye those freezes stopped, I was happy it got fixed, but then once I did clean installation of Bullseye those freezes started again as in Buster. I am at loss why.
I have Radeon HD 7450M and have installed necessary non-free firmware as before. And I have no clue where to even look as to possible issue, it is even more confusing to me that it worked great after upgrade. But not after clean installation. I have followed wiki on ATI card setup
Firmware, is loaded, no issues such as warnings/error are shown in journal, no output in console when running unity game. I am have hybrid graphics so I run it using DRI_PRIME offloading, I have checked and it does run on radeon.
Another thing is that radeontop shows odd results, even when not in use I have wrong reading, example right now
Code: Select all
4457M / 1024M VRAM 435.27% │ 2183M / 1018M GTT 214.43% │ 0.90G / 0.00G Memory Clock inf% │ 0.75G / 0.75G Shader Clock 100.00% │
Clearly those are wrong and not possible. Could it be some kind of bug or something on my end? I don't know where to even look for start of those issues. If anyone knows anything please say.
