Description network723 2017-07-26 15:44:19 UTC

I've tried building Mesa-git 31f1863ace73d31a579e5c36252a957818ad09cf, and when I run KDE Plasma 5.8 session, it shows that about 4 Gigabytes of RAM is used. Memory isn't freed if I shut down KDE session and kill display manager, the only way to get it back is rebooting. IceWM session works fine.
With Mesa-git of July 22nd memory footprint in KDE was about 600 megabytes.

Distro: openSUSE 42.2
Hardware: AMD RX480

There was a leak introduced with bbc29393d3beaf6344c7188547b4ff61b63946ae which was be resolved by 914f11e75b8ebe8a0faab76ce25fe185ab580eee.

Can you give that a try?

Tried building the 914f11e75b8ebe8a0faab76ce25fe185ab580eee, looks like it's not the case, memory usage is still ridiculously high. Btw, i noticed that KDE starts really slow, and there is unusually much disk activity. Maybe it's somehow related to on-disk shader cache?

Hi all,

I also have this issue, and I have bisected it to the commit Emil mentions, but I can confirm that the suggested fix doesn't work.

Thanks,
Sarnex
